CVE-2026-72463

In the Linux kernel, the following vulnerability has been resolved: xfrm: Fix dev use-after-free in xfrm async resumption xfrm async resumption hold skb-dev refcnt until after transportfinish. However, xfrmrcvcb may modify skb-dev to tunnel dev without taking device reference, such as vtircvcb. T...

CVE-2026-72451

In the Linux kernel, the following vulnerability has been resolved: xfrm: Fix xfrm state cache insertion race The xfrm input state cache insertion code checks the validity of the state before acquiring the global xfrmstatelock. Thus it's possible for someone else to kill the state after it passed...

In the Linux kernel, the following vulnerability has been resolved: xfrm: validate selector family and prefixlen during match syzbot reported a shift-out-of-bounds in xfrmselectormatch due to AFUNSPEC selector with large prefixlen e.g. 128 matched against IPv4 flow when XFRMSTATEAFUNSPEC is set...

CVE-2026-72137

In the Linux kernel, the following vulnerability has been resolved: xfrm: natkeepalive: avoid double free on send error natkeepalivesend frees the keepalive skb whenever the IPv4 or IPv6 send helper reports an error. That cleanup is only correct before the skb is handed to the output path. Once...

CVE-2026-72463

The CVE-2026-72463 entry concerns the Linux kernel: “xfrm: Fix dev use-after-free in xfrm async resumption.” The issue arises because xfrm_rcv_cb may modify skb->dev to a tunnel device without taking a device reference, and the subsequent async resumption decrements the tunnel device’s refcoun...

CVE-2026-72451

CVE-2026-72451 concerns the Linux kernel’s xfrm subsystem. The vulnerability arises in the xfrm input state cache insertion, where the code validates a state’s validity before acquiring the global xfrm_state_lock. If the state is killed after the initial check but before insertion, a dead state c...

CVE-2026-72450

CVE-2026-72450 affects the Linux kernel’s xfrm subsystem. Syzbot reported a shift-out-of-bounds in xfrm_selector_match when an AF_UNSPEC selector with a large prefixlen (e.g., 128) is matched against IPv4 flows under XFRM_STATE_AF_UNSPEC. The fix conceptually: (1) reject mismatched families in xf...

CVE-2026-72137

CVE-2026-72137 — Linux kernel xfrm: nat_keepalive double‑free fix . Public docs describe a bug where nat_keepalive_send() could try to free the keepalive skb after the IPv4/IPv6 send helper reports an error, which could be unsafe once the packet is handed to the output path. The fix moves pre‑han...
