Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference due to improper error handling in the io_alloc_pbuf_ring function. An attacker can cause a denial of service by exploiting the inconsistent handling of NULL vs IS_ERR values. This is only exploitable if the system is configured to use io_uring with specific buffer settings.
