CVE-2026-23254

CVE-2026-23254 (Linux kernel): The issue affects UDP GRO in the net/ gro path, where the complete stage incorrectly uses the inner network offset when the encapsulation flag is not reliably zeroed by hardware offloads. The root cause is an assumption that all RX-inserted packets have encapsulatio...

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...
