What to do

AI-suggested

A fix for this vulnerability has been implemented in the Linux kernel. Users should apply the official kernel updates that include this fix. Since no specific patch links are provided, consult the Linux kernel vendor advisories or mainline kernel repositories for the corrected versions.

Description

A vulnerability in the Linux kernel's network scheduler (net/sched) involving mirred redirect loops between ingress and egress interfaces has been fixed. The flaw caused loss of loop state detection due to packet deferral and clearing of internal state arrays, potentially allowing undetected mirred loops.
