No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The aio_aqueue function, used by the lio_listio system call, fails to release a reference to a credential in an error case.

An attacker may cause the reference count to overflow, leading to a use after free (UAF).
