CVE-2022-4269

Quick assessment

Affected
n/a Linux kernel (TC subsystem)
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel存在安全漏洞，该漏洞源于Traffic Control (TC) subsystem存在一个缺陷，使用特定的网络配置（使用 TC 操作“mirred”将出口数据包重定向到入口），当使用的传输协议（TCP 或 SCTP）进行重传时，本地非特权用户可能会触发 CPU 软锁定（ABBA 死锁），从而导致 拒绝服务条件。

N/A
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking configuration (redirecting egress packets to ingress using TC action "mirred") a local unprivileged user could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a retransmission, resulting in a denial of service condition.
