RDMA/bnxt_re: Avoid clearing VLAN_ID mask in modify qp path stable inclusion from stable-6.6.85 commit dba5577d8e3317801201f9745b65b60b1454e1f0 category: bugfix issue: #IC1IVT CVE: NA Signed-off-by: zyf1116 <zhouyongfei3@huawei.com> --------------------------------------- [ Upstream commit 81c0db302a674f8004ed805393d17fd76f552e83 ] Driver is always clearing the mask that sets the VLAN ID/Service Level in the adapter. Recent change for supporting multiple traffic class exposed this issue. Allow setting SL and VLAN_ID while QP is moved from INIT to RTR state.

rdma/cxgb4: Prevent potential integer overflow on 32bit stable inclusion from stable-6.6.76 commit de8d88b68d0cfd41152a7a63d6aec0ed3e1b837a category: bugfix issue: #IBLFX7 CVE: NA Signed-off-by: zyf1116 <zhouyongfei3@huawei.com> --------------------------------------- [ Upstream commit bd96a3935e89486304461a21752f824fc25e0f0b ] The "gl->tot_len" variable is controlled by the user. It comes from process_responses(). On 32bit systems, the "gl->tot_len + sizeof(struct cpl_pass_accept_req) + sizeof(struct rss_header)" addition could have an integer wrapping bug.

RDMA/irdma: avoid invalid read in irdma_net_event stable inclusion from stable-6.6.105 commit 6f05611728e9 category: bugfix issue: #223 CVE: CVE-2025-71133 Signed-off-by: zxl <1554188414@qq.com> ------------------------------- RDMA/irdma: avoid invalid read in irdma_net_event irdma_net_event() should not dereference anything from "neigh" (alias "ptr") until it has checked that the event is NETEVENT_NEIGH_UPDATE. Other events come with different structures pointed to by "ptr" and they may be smaller than struct neighbour. Move the read of neigh->dev under the NETEVENT_NEIGH_UPDATE case. The bug is mostly harmless, but it triggers KASAN on debug kernels: BUG: KASAN: stack-out-of-bounds in irdma_net_event+0x32e/0x3b0 [irdma] Read of size 8 at addr ffffc900075e07f0 by task kworker/27:2/542554 CPU: 27 PID: 542554 Comm: kworker/27:2 Kdump: loaded Not tainted 5.14.0-630.el9.x86_64+debug #1 Hardware name: [...] Workqueue: events rt6_probe_deferred Call Trace: <IRQ> dump_stack_lvl+0x60/0xb0 print_address_description.constprop.0+0x2c/0x3f0 print_report+0xb4/0x270 kasan_report+0x92/0xc0 irdma_net_event+0x32e/0x3b0 [irdma] notifier_call_chain+0x9e/0x180 atomic_notifier_call_chain+0x5c/0x110 rt6_do_redirect+0xb91/0x1080 tcp_v6_err+0xe9b/0x13e0 icmpv6_notify+0x2b2/0x630 ndisc_redirect_rcv+0x328/0x530 icmpv6_rcv+0xc16/0x1360 ip6_protocol_deliver_rcu+0xb84/0x12e0 ip6_input_finish+0x117/0x240 ip6_input+0xc4/0x370 ipv6_rcv+0x420/0x7d0 __netif_receive_skb_one_core+0x118/0x1b0 process_backlog+0xd1/0x5d0 __napi_poll.constprop.0+0xa3/0x440 net_rx_action+0x78a/0xba0 handle_softirqs+0x2d4/0x9c0 do_softirq+0xad/0xe0 </IRQ> Fixes: 915cc7ac0f8e ("RDMA/irdma: Add miscellaneous utility definitions") Link: https://patch.msgid.link/r/20251127143150.121099-1-mschmidt@redhat.com Signed-off-by: Michal Schmidt <mschmidt@redhat.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com> Signed-off-by: zxl <1554188414@qq.com> | 6 个月前 | |
