In the Linux kernel, the following vulnerability has been resolved: net/sched: Fix ethx:ingress - ethy:egress - ethx:ingress mirred loop When mirred redirects to ingress from either ingress or egress the loop state from schedmirreddev array dev is lost because of 1 the packet deferral into the...

CVE-2026-63982

This CVE concerns the Linux kernel net/sched mirred loop where redirecting between ingress and egress could lose the loop state in sched_mirred_dev, preventing discovery of a loop. The issue arises when packets are deferred to backlog and the sched_mirred_dev array is cleared, causing loop state ...
