CVE-2026-23095

CVE-2026-23095 affects the Linux kernel Gue (GUE) path. It describes a skb memory leak when inner IP protocol is 0, triggered by a GUE repro. The issue arises because gue_udp_recv() may propagate a zero protocol, causing a memory leak; the fix drops such packets. The description notes that 0 is a...
