漏洞简述:
In the Linux kernel, the following vulnerability has been resolved:IB/isert: reject login PDUs declaring more data than was receivedisert_login_recv_done() records how many bytes the HCA actually placed inthe login buffer, but nothing compares that against the length the loginPDU s BHS declares. isert_rx_login_req() copies min(login_req_len,MAX_KEY_VALUE_PAIRS) bytes into login->req_buf, and the login code thenreads the declared length back out of that buffer - for the first PDU iniscsi_target_locate_portal(), payload_length = ntoh24(login_req->dlength); tmpbuf = kmemdup_nul(login->req_buf, payload_length, GFP_KERNEL);and for the ones after it in iscsi_decode_text_input(), reached fromiscsi_target_do_login().login->req_buf is a fixed MAX_KEY_VALUE_PAIRS (8192) byte allocation, soan initiator that declares more than it sends reads off the end of it,before authentication and with the length under its control: BUG: KASAN: slab-out-of-bounds in kmemdup_nul+0x43/0x80 Read of size 8193 at addr ffff8881056a8000 by task iscsi_np/167 __asan_memcpy+0x23/0x60 kmemdup_nul+0x43/0x80 iscsi_target_locate_portal+0x48d/0x1180 iscsi_target_login_thread+0x19a9/0x3350 Allocated by task 167: __kmalloc_cache_noprof+0x158/0x370 iscsi_target_login_thread+0x971/0x3350 which belongs to the cache kmalloc-8k of size 8192 allocated 8192-byte regionFalsifying the second login PDU instead reaches the other reader, on thesame buffer: BUG: KASAN: slab-out-of-bounds in kmemdup_nul+0x43/0x80 Read of size 8193 at addr ffff888104d10000 by task kworker/1:1/50 Workqueue: isert_login_wq iscsi_target_do_login_rx __asan_memcpy+0x23/0x60 kmemdup_nul+0x43/0x80 iscsi_decode_text_input+0xc6/0x11c0 iscsi_target_do_login+0x261/0x1470 iscsi_target_do_login_rx+0x51d/0x7d0iscsit over TCP is not exposed: iscsit_get_login_rx() validates thedeclared length with iscsi_target_check_login_request() and then readsexactly that many bytes off the socket, so the declared length governshow much arrives rather than how much is copied out of an already-filledbuffer. isert does not call iscsi_target_check_login_request() at all.Reject a login PDU whose declared DataSegmentLength exceeds what wasreceived, in both paths that reach isert_rx_login_req():isert_get_login_rx() for the first login PDU and isert_login_recv_done()for the ones after it. dlength <= login_req_len is allowed because thereceived count can include up to three bytes of iSCSI padding.Once the check is in place the copy out can no longer exceed the copy in:the posted login SGE is ISER_RX_PAYLOAD_SIZE, so login_req_len cannotexceed MAX_KEY_VALUE_PAIRS and the min() in isert_rx_login_req() islogin_req_len.Like the existing short-PDU check added by 29e7b925ae6d, the reject inisert_login_recv_done() returns without completing login_req_comp, so amalformed subsequent PDU leaves the login to be torn down by the logintimer rather than failing immediately. The first-PDU path returns anerror and fails straight away.Reproduced on 7.2.0-rc4 with soft-RoCE (rdma_rxe) under KASAN, using aninitiator that sends the real key=value payload while declaring 8193 inthe BHS, on the first login PDU and on the second in separate runs. Thereported read size tracks the declared value exactly; 16384 and 61440behave the same. Unpatched 3 of 3 runs report on each of the two paths,patched 0 of 3 on both, run alternately in a single session, and a normallogin still completes on the patched build.

原因说明填写请参考下方表格(注意:版本是否受影响和版本的原因说明必须对应,例如master版本分支受影响,那原因说明只能是受影响对应的原因之一!):

分支状态
原因说明 使用场景
受影响 正常修复 受影响且需要修复(包含升级版本修复)的漏洞;
受影响且已经修复的漏洞(历史修复PR也需要关联issue);
若因特殊原因无法修复,应修改原因说明为【不修复-特殊原因】,并在安委会备案相关情况。
受影响 暂不修复-漏洞仍在分析中 已关注到相关漏洞,正在处理,未明确漏洞影响和修复方案。
受影响 暂不修复-暂无解决方案或补丁 当前没有可用的修复或补救措施。【影响性分析】中应包含有关为什么没有修复或补救措施的详细说明、上游相关PR等。
受影响 不修复-超出修复范围 没有漏洞的修复计划。当版本停维、软件包宣布生命周期终止或弃用使用。
受影响 不修复-特殊原因导致不再修复 如存在其他特殊情况不修复相关漏洞,或评估后无法升级修复,应在openEuler社区安全委员会例会进行说明备案。
【影响性分析】中应包含不发布修复的详细说明、特殊情况还应有安委会会议纪要。
不受影响 不受影响-组件不存在 软件不受影响,因为易受攻击的组件不在产品中。
不受影响 不受影响-已有内置的内联控制或缓解措施 内置的内联控制或缓解措施可防止攻击者利用漏洞
不受影响 不受影响-漏洞代码不能被攻击者触发 易受攻击的组件存在,并且该组件包含易受攻击的代码。但是,易受攻击的代码的使用方式使得攻击者无法进行任何预期的攻击。
不受影响 不受影响-漏洞代码不在执行路径 易受影响的代码在执行过程中不可访问,包括产品的非预期状态。产品不使用也不执行的组件。
不受影响 不受影响-漏洞代码不存在 产品不受影响,因为漏洞背后的代码在产品中不存在。与component_not_present不同的是,有问题的组件存在,但由于某种原因(例如安全的编译器选项)使漏洞的特定代码不存在于组件中。

CVE-2026-90413

影响性分析说明:
In the Linux kernel, the following vulnerability has been resolved:

IB/isert: reject login PDUs declaring more data than was received

isert_login_recv_done() records how many bytes the HCA actually placed in
the login buffer, but nothing compares that against the length the login
PDU's BHS declares. isert_rx_login_req() copies min(login_req_len,
MAX_KEY_VALUE_PAIRS) bytes into login->req_buf, and the login code then
reads the declared length back out of that buffer - for the first PDU in
iscsi_target_locate_portal(),

payload_length = ntoh24(login_req->dlength);
tmpbuf = kmemdup_nul(login->req_buf, payload_length, GFP_KERNEL);

and for the ones after it in iscsi_decode_text_input(), reached from
iscsi_target_do_login().

login->req_buf is a fixed MAX_KEY_VALUE_PAIRS (8192) byte allocation, so
an initiator that declares more than it sends reads off the end of it,
before authentication and with the length under its control:

BUG: KASAN: slab-out-of-bounds in kmemdup_nul+0x43/0x80
Read of size 8193 at addr ffff8881056a8000 by task iscsi_np/167
__asan_memcpy+0x23/0x60
kmemdup_nul+0x43/0x80
iscsi_target_locate_portal+0x48d/0x1180

Allocated by task 167:
__kmalloc_cache_noprof+0x158/0x370
iscsi_target_login_thread+0x971/0x3350
which belongs to the cache kmalloc-8k of size 8192
allocated 8192-byte region

Falsifying the second login PDU instead reaches the other reader, on the
same buffer:

BUG: KASAN: slab-out-of-bounds in kmemdup_nul+0x43/0x80
Read of size 8193 at addr ffff888104d10000 by task kworker/1:1/50

iscsi_target_do_login+0x261/0x1470
iscsi_target_do_login_rx+0x51d/0x7d0

iscsit over TCP is not exposed: iscsit_get_login_rx() validates the
declared length with iscsi_target_check_login_request() and then reads
exactly that many bytes off the socket, so the declared length governs
how much arrives rather than how much is copied out of an already-filled
buffer. isert does not call iscsi_target_check_login_request() at all.

Reject a login PDU whose declared DataSegmentLength exceeds what was
received, in both paths that reach isert_rx_login_req():
isert_get_login_rx() for the first login PDU and isert_login_recv_done()
for the ones after it. dlength <= login_req_len is allowed because the
received count can include up to three bytes of iSCSI padding.

Once the check is in place the copy out can no longer exceed the copy in:
the posted login SGE is ISER_RX_PAYLOAD_SIZE, so login_req_len cannot
exceed MAX_KEY_VALUE_PAIRS and the min() in isert_rx_login_req() is
login_req_len.

Like the existing short-PDU check added by 29e7b925ae6d, the reject in
isert_login_recv_done() returns without completing login_req_comp, so a
malformed subsequent PDU leaves the login to be torn down by the login
timer rather than failing immediately. The first-PDU path returns an
error and fails straight away.

Reproduced on 7.2.0-rc4 with soft-RoCE (rdma_rxe) under KASAN, using an
initiator that sends the real key=value payload while declaring 8193 in
the BHS, on the first login PDU and on the second in separate runs. The
reported read size tracks the declared value exactly; 16384 and 61440
behave the same. Unpatched 3 of 3 runs report on each of the two paths,
patched 0 of 3 on both, run alternately in a single session, and a normal
login still completes on the patched build.

CVE-2026-90413

影响性分析说明:
In the Linux kernel, the following vulnerability has been resolved:

IB/isert: reject login PDUs declaring more data than was received

isert_login_recv_done() records how many bytes the HCA actually placed in
the login buffer, but nothing compares that against the length the login
PDU's BHS declares. isert_rx_login_req() copies min(login_req_len,
MAX_KEY_VALUE_PAIRS) bytes into login->req_buf, and the login code then
reads the declared length back out of that buffer - for the first PDU in
iscsi_target_locate_portal(),

payload_length = ntoh24(login_req->dlength);
tmpbuf = kmemdup_nul(login->req_buf, payload_length, GFP_KERNEL);

and for the ones after it in iscsi_decode_text_input(), reached from
iscsi_target_do_login().

login->req_buf is a fixed MAX_KEY_VALUE_PAIRS (8192) byte allocation, so
an initiator that declares more than it sends reads off the end of it,
before authentication and with the length under its control:

BUG: KASAN: slab-out-of-bounds in kmemdup_nul+0x43/0x80
Read of size 8193 at addr ffff8881056a8000 by task iscsi_np/167
__asan_memcpy+0x23/0x60
kmemdup_nul+0x43/0x80
iscsi_target_locate_portal+0x48d/0x1180
iscsi_target_login_thread+0x19a9/0x3350
Allocated by task 167:
__kmalloc_cache_noprof+0x158/0x370
iscsi_target_login_thread+0x971/0x3350
which belongs to the cache kmalloc-8k of size 8192
allocated 8192-byte region

Falsifying the second login PDU instead reaches the other reader, on the
same buffer:

BUG: KASAN: slab-out-of-bounds in kmemdup_nul+0x43/0x80
Read of size 8193 at addr ffff888104d10000 by task kworker/1:1/50
Workqueue: isert_login_wq iscsi_target_do_login_rx
__asan_memcpy+0x23/0x60
kmemdup_nul+0x43/0x80
iscsi_decode_text_input+0xc6/0x11c0
iscsi_target_do_login+0x261/0x1470
iscsi_target_do_login_rx+0x51d/0x7d0

iscsit over TCP is not exposed: iscsit_get_login_rx() validates the
declared length with iscsi_target_check_login_request() and then reads
exactly that many bytes off the socket, so the declared length governs
how much arrives rather than how much is copied out of an already-filled
buffer. isert does not call iscsi_target_check_login_request() at all.

Reject a login PDU whose declared DataSegmentLength exceeds what was
received, in both paths that reach isert_rx_login_req():
isert_get_login_rx() for the first login PDU and isert_login_recv_done()
for the ones after it. dlength <= login_req_len is allowed because the
received count can include up to three bytes of iSCSI padding.

Once the check is in place the copy out can no longer exceed the copy in:
the posted login SGE is ISER_RX_PAYLOAD_SIZE, so login_req_len cannot
exceed MAX_KEY_VALUE_PAIRS and the min() in isert_rx_login_req() is
login_req_len.

Like the existing short-PDU check added by 29e7b925ae6d, the reject in
isert_login_recv_done() returns without completing login_req_comp, so a
malformed subsequent PDU leaves the login to be torn down by the login
timer rather than failing immediately. The first-PDU path returns an
error and fails straight away.

Reproduced on 7.2.0-rc4 with soft-RoCE (rdma_rxe) under KASAN, using an
initiator that sends the real key=value payload while declaring 8193 in
the BHS, on the first login PDU and on the second in separate runs. The
reported read size tracks the declared value exactly; 16384 and 61440
behave the same. Unpatched 3 of 3 runs report on each of the two paths,
patched 0 of 3 on both, run alternately in a single session, and a normal
login still completes on the patched build.

CVE-2026-90413

影响性分析说明:
In the Linux kernel, the following vulnerability has been resolved:

IB/isert: reject login PDUs declaring more data than was received

isert_login_recv_done() records how many bytes the HCA actually placed in
the login buffer, but nothing compares that against the length the login
PDU's BHS declares. isert_rx_login_req() copies min(login_req_len,
MAX_KEY_VALUE_PAIRS) bytes into login->req_buf, and the login code then
reads the declared length back out of that buffer - for the first PDU in
iscsi_target_locate_portal(),

payload_length = ntoh24(login_req->dlength);
tmpbuf = kmemdup_nul(login->req_buf, payload_length, GFP_KERNEL);

and for the ones after it in iscsi_decode_text_input(), reached from
iscsi_target_do_login().

login->req_buf is a fixed MAX_KEY_VALUE_PAIRS (8192) byte allocation, so
an initiator that declares more than it sends reads off the end of it,
before authentication and with the length under its control:

BUG: KASAN: slab-out-of-bounds in kmemdup_nul+0x43/0x80

Falsifying the second login PDU instead reaches the other reader, on the

CVE-2026-90413

影响性分析说明:
In the Linux kernel, the following vulnerability has been resolved:

IB/isert: reject login PDUs declaring more data than was received

isert_login_recv_done() records how many bytes the HCA actually placed in
the login buffer, but nothing compares that against the length the login
PDU's BHS declares. isert_rx_login_req() copies min(login_req_len,
MAX_KEY_VALUE_PAIRS) bytes into login->req_buf, and the login code then
reads the declared length back out of that buffer - for the first PDU in
iscsi_target_locate_portal(),

payload_length = ntoh24(login_req->dlength);
tmpbuf = kmemdup_nul(login->req_buf, payload_length, GFP_KERNEL);

and for the ones after it in iscsi_decode_text_input(), reached from
iscsi_target_do_login().

login->req_buf is a fixed MAX_KEY_VALUE_PAIRS (8192) byte allocation, so
an initiator that declares more than it sends reads off the end of it,
before authentication and with the length under its control:

BUG: KASAN: slab-out-of-bounds in kmemdup_nul+0x43/0x80
Read of size 8193 at addr ffff8881056a8000 by task iscsi_np/167
__asan_memcpy+0x23/0x60
kmemdup_nul+0x43/0x80
iscsi_target_locate_portal+0x48d/0x1180
iscsi_target_login_thread+0x19a9/0x3350
Allocated by task 167:
__kmalloc_cache_noprof+0x158/0x370
iscsi_target_login_thread+0x971/0x3350
which belongs to the cache kmalloc-8k of size 8192
allocated 8192-byte region

Falsifying the second login PDU instead reaches the other reader, on the
same buffer:

BUG: KASAN: slab-out-of-bounds in kmemdup_nul+0x43/0x80
Read of size 8193 at addr ffff888104d10000 by task kworker/1:1/50
Workqueue: isert_login_wq iscsi_target_do_login_rx
__asan_memcpy+0x23/0x60
kmemdup_nul+0x43/0x80
iscsi_decode_text_input+0xc6/0x11c0
iscsi_target_do_login+0x261/0x1470
iscsi_target_do_login_rx+0x51d/0x7d0

iscsit over TCP is not exposed: iscsit_get_login_rx() validates the
declared length with iscsi_target_check_login_request() and then reads
exactly that many bytes off the socket, so the declared length governs
how much arrives rather than how much is copied out of an already-filled
buffer. isert does not call iscsi_target_check_login_request() at all.

Reject a login PDU whose declared DataSegmentLength exceeds what was
received, in both paths that reach isert_rx_login_req():
isert_get_login_rx() for the first login PDU and isert_login_recv_done()
for the ones after it. dlength <= login_req_len is allowed because the
received count can include up to three bytes of iSCSI padding.

Once the check is in place the copy out can no longer exceed the copy in:
the posted login SGE is ISER_RX_PAYLOAD_SIZE, so login_req_len cannot
exceed MAX_KEY_VALUE_PAIRS and the min() in isert_rx_login_req() is
login_req_len.

Like the existing short-PDU check added by 29e7b925ae6d, the reject in
isert_login_recv_done() returns without completing login_req_comp, so a
malformed subsequent PDU leaves the login to be torn down by the login
timer rather than failing immediately. The first-PDU path returns an
error and fails straight away.

Reproduced on 7.2.0-rc4 with soft-RoCE (rdma_rxe) under KASAN, using an
initiator that sends the real key=value payload while declaring 8193 in
the BHS, on the first login PDU and on the second in separate runs. The
reported read size tracks the declared value exactly; 16384 and 61440
behave the same. Unpatched 3 of 3 runs report on each of the two paths,
patched 0 of 3 on both, run alternately in a single session, and a normal
login still completes on the patched build.

CVE-2026-90413

影响性分析说明:
In the Linux kernel, the following vulnerability has been resolved:

IB/isert: reject login PDUs declaring more data than was received

isert_login_recv_done() records how many bytes the HCA actually placed in
the login buffer, but nothing compares that against the length the login
PDU's BHS declares. isert_rx_login_req() copies min(login_req_len,
MAX_KEY_VALUE_PAIRS) bytes into login->req_buf, and the login code then
reads the declared length back out of that buffer - for the first PDU in
iscsi_target_locate_portal(),

payload_length = ntoh24(login_req->dlength);
tmpbuf = kmemdup_nul(login->req_buf, payload_length, GFP_KERNEL);

and for the ones after it in iscsi_decode_text_input(), reached from
iscsi_target_do_login().

login->req_buf is a fixed MAX_KEY_VALUE_PAIRS (8192) byte allocation, so
an initiator that declares more than it sends reads off the end of it,
before authentication and with the length under its control:

BUG: KASAN: slab-out-of-bounds in kmemdup_nul+0x43/0x80
Read of size 8193 at addr ffff8881056a8000 by task iscsi_np/167
__asan_memcpy+0x23/0x60
kmemdup_nul+0x43/0x80
iscsi_target_locate_portal+0x48d/0x1180
iscsi_target_login_thread+0x19a9/0x3350
Allocated by task 167:
__kmalloc_cache_noprof+0x158/0x370
iscsi_target_login_thread+0x971/0x3350
which belongs to the cache kmalloc-8k of size 8192
allocated 8192-byte region

Falsifying the second login PDU instead reaches the other reader, on the
same buffer:

BUG: KASAN: slab-out-of-bounds in kmemdup_nul+0x43/0x80
Read of size 8193 at addr ffff888104d10000 by task kworker/1:1/50
Workqueue: isert_login_wq iscsi_target_do_login_rx
__asan_memcpy+0x23/0x60
kmemdup_nul+0x43/0x80
iscsi_decode_text_input+0xc6/0x11c0
iscsi_target_do_login+0x261/0x1470
iscsi_target_do_login_rx+0x51d/0x7d0

iscsit over TCP is not exposed: iscsit_get_login_rx() validates the
declared length with iscsi_target_check_login_request() and then reads
exactly that many bytes off the socket, so the declared length governs
how much arrives rather than how much is copied out of an already-filled
buffer. isert does not call iscsi_target_check_login_request() at all.

Reject a login PDU whose declared DataSegmentLength exceeds what was
received, in both paths that reach isert_rx_login_req():
isert_get_login_rx() for the first login PDU and isert_login_recv_done()
for the ones after it. dlength <= login_req_len is allowed because the
received count can include up to three bytes of iSCSI padding.

Once the check is in place the copy out can no longer exceed the copy in:
the posted login SGE is ISER_RX_PAYLOAD_SIZE, so login_req_len cannot
exceed MAX_KEY_VALUE_PAIRS and the min() in isert_rx_login_req() is
login_req_len.

Like the existing short-PDU check added by 29e7b925ae6d, the reject in
isert_login_recv_done() returns without completing login_req_comp, so a
malformed subsequent PDU leaves the login to be torn down by the login
timer rather than failing immediately. The first-PDU path returns an
error and fails straight away.

Reproduced on 7.2.0-rc4 with soft-RoCE (rdma_rxe) under KASAN, using an
initiator that sends the real key=value payload while declaring 8193 in
the BHS, on the first login PDU and on the second in separate runs. The
reported read size tracks the declared value exactly; 16384 and 61440
behave the same. Unpatched 3 of 3 runs report on each of the two paths,
patched 0 of 3 on both, run alternately in a single session, and a normal
login still completes on the patched build.
