CVE-2026-80634

A flaw was found in the Linux kernel's netfilter flowtable component. An integer underflow can occur during bridge Virtual Local Area Network VLAN untagging operations. If the numencaps value is zero, a decrement operation can cause it to wrap to 255. This can lead to an out-of-bounds stack read...

CVE-2026-80634

CVE-2026-80634 is a Linux kernel vulnerability in the netfilter flowtable subsystem. The root cause is an integer underflow: in the DEV_PATH_BR_VLAN_UNTAG path, info->num_encaps (a u8) is post-decremented inside WARN_ON_ONCE(), wrapping to 255 when already zero. This causes nft_dev_forward_pat...
