CVE-2026-72348

A flaw was found in the Linux kernel's netfilter subsystem, specifically within ip6tables. A remote attacker could send specially crafted IPv6 packets with malformed extension headers. Due to improper length checks, these malformed packets might not be correctly identified and dropped by ip6table...

CVE-2026-74579

A flaw was found in the Linux kernel's netfilter subsystem. The nftpayloadoffloadmask function, which builds offload match masks for network packet header fields, contains a shift-out-of-bounds error. This occurs when processing partial IPv6 address matches, leading to an incorrect mask calculati...
