CVE-2026-23456

A flaw was found in the Linux kernel's netfilter H.323 connection tracking module. A remote attacker could exploit this vulnerability by sending a specially crafted H.323/RAS H.323 Registration, Admission, and Status packet. The system's processing of these packets could lead to an out-of-bounds...
