CVE-2026-64581

CVE-2026-64581 is a Linux kernel vulnerability in the xfrm code. The issue arises in xfrm_user_policy(), which clears the socket destination cache (sk_dst_cache) non‑atomically, allowing a race with a per‑socket policy change that can cause the same dst to be released twice, freeing the xfrm_dst ...
