CVE-2026-31517

The CVE-2026-31517 vulnerability affects the Linux kernel’s IP-TFS (xfrm_iptfs) reassembly path. During datagram reassembly, an optimization can make newskb non-linear; if a subsequent fragment is appended via skb_put(), the code may trigger a SKB_LINEAR_ASSERT and crash (OOPS). The documented fi...
