CVE-2026-43916

pamauthnft is a PAM session module binding nftables firewall rules to authenticated sessions via cgroupv2 inodes. Prior to 0.2.0-alpha, a heap buffer over-read in peerlookuptcp src/peerlookup.c:134, prior to the fix allowed a crafted NETLINKSOCKDIAG reply to slip past the message-size check, then...

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftinner: Fix IPv6 innerthoff desync In nftinnerparsel2l3, when processing inner IPv6 packets, ipv6findhdr correctly computes the transport header offset traversing all extension headers, but the result is immediately...

CVE-2026-46244

The CVE-2026-46244 issue affects the Linux kernel netfilter nft_inner path. In nft_inner_parse_l2l3(), while handling inner IPv6 packets, ipv6_find_hdr() computes the transport header offset correctly across extension headers, but the code later overwrites this value with nhoff + sizeof(_ip6h) (4...
