CVE-2026-31664

The CVE-2026-31664 issue resides in the Linux kernel xfrm subsystem: build_polexpire() fails to clear trailing padding in struct xfrm_user_polexpire, leaving uninitialized heap bytes that are sent to userspace via netlink multicast (XFRMNLGRP_EXPIRE). The consequence is potential leakage of kerne...
