漏洞简述:
In the Linux kernel, the following vulnerability has been resolved:sctp: keep chunk->transport in step with the list it is queued on__sctp_outq_flush_rtx() moves a gap-acked chunk onto another transport stransmitted list without updating chunk->transport: if (chunk->tsn_gap_acked) { list_move_tail(&chunk->transmitted_list, &transport->transmitted); continue; }The chunk then sits on a live transport s list while chunk->transport stillnames a different one. If that transport is removed - sctp_assoc_rm_peer()from an ASCONF Delete-IP - sctp_transport_free() RCU-frees it and the chunkis left with a dangling pointer. sctp_assoc_rm_peer() scrubspeer->transmitted and asoc->outqueue.out_chunk_list, but the chunk is onneither.The pointer is not followed while tsn_gap_acked is set. A SACK thatreneges on the TSN clears the flag, and the next SACK reaches tchunk->transport->flight_size -= sctp_data_size(tchunk);inside the freed transport. KASAN reports a slab-use-after-free read insctp_check_transmitted(), freed from sctp_assoc_rm_peer(). Both theremoval and the SACKs come from the association peer.Set chunk->transport at the move. The ordinary resend path needs nothing:it reaches its list_move_tail() only after sctp_packet_append_chunk()returned SCTP_XMIT_OK, and __sctp_packet_append_chunk() has rebound thechunk by then.Discovered by XBOW, triaged by Baul Lee baul.lee@xbow.com

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 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。
