CVE-2026-31664

A flaw was found in the Linux kernel's xfrm subsystem. This vulnerability arises because the buildpolexpire function does not clear trailing padding bytes within the xfrmuserpolexpire structure. Consequently, these uninitialized padding bytes, which contain kernel heap memory contents, are sent t...

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...
