CVE-2026-53267
The CVE-2026-53267 entry concerns a Linux kernel netfilter nft_ct use-after-free style issue where a per-CPU template conntrack entry can be treated as a real ct, causing a 16-byte memcpy path to overflow the kernel stack when using NFT_REG32_15. The root cause is that a template ct is not reject...
