Descriptions

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).

La función aio_aqueue, utilizada por la llamada al sistema lio_listio, no puede liberar una referencia a una credencial en un caso de error. Un atacante puede provocar que el recuento de referencias se desborde, lo que provocará un use after free (UAF).
