CVE-2026-52912

A flaw was found in the Linux kernel's netfilter component. This vulnerability occurs because a queued bridge packet can retain a freed bridge master in its skb-dev field until it is reinjected. When the packet is later reinjected, the system attempts to use the freed bridge master, leading to a...

CVE-2026-52912

The CVE-2026-52912 affects the Linux kernel netfilter nf_queue handling of bridge LOCAL_IN traffic. br_pass_frame_up() rewrites skb->dev from the ingress port to the bridge master before queueing, allowing a queued bridge packet to retain a freed bridge master in skb->dev. On reinjection, b...
