CVE-2026-72254

The CVE-2026-72254 entry concerns the Linux kernel netfilter NFT_FIB logic. A fib expression in a netdev egress base chain could dereference nft_in(pkt) on the transmit path, yielding a NULL pointer dereference during eval. The root cause is that nft_fib_validate() masks the hook with NF_INET_* v...
