SUSE CVE-2026-31663

In the Linux kernel, the following vulnerability has been resolved: xfrm: hold dev ref until after transportfinish NFHOOK After async crypto completes, xfrminputresume calls devput immediately on re-entry before the skb reaches transportfinish. The skb-dev pointer is then used inside NFHOOK and i...

CVE-2026-31663 xfrm: hold dev ref until after transport_finish NF_HOOK

In the Linux kernel, the following vulnerability has been resolved: xfrm: hold dev ref until after transportfinish NFHOOK After async crypto completes, xfrminputresume calls devput immediately on re-entry before the skb reaches transportfinish.

CVE-2026-31663

The CVE-2026-31663 vulnerability affects the Linux kernel xfrm subsystem, where a race between asynchronous crypto completion and device teardown could lead to using a freed dev reference. The fix changes the reference handling: the dev ref is no longer released on async resume entry and is inste...

SUSE CVE-2024-40983

In the Linux kernel, the following vulnerability has been resolved: tipc: force a dst refcount before doing decryption As it says in commit 3bc07321ccc2 "xfrm: Force a dst refcount before entering the xfrm type handlers": "Crypto requests might return asynchronous. In this case we leave the rcu...

kernel: tls: race between async notify and socket close

A race condition vulnerability was found in the tls subsystem of the Linux kernel. The submitting thread that calls recvmsg/sendmsg may exit as soon as the async crypto handler calls complete; any code past that point risks touching already freed data. This could lead to a use-after-free issue an...
