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...
