CVE-2023-52811

In CVE-2023-52811, the Linux kernel ibmvfc driver fix removes a BUG_ON when an event pool is empty and instead returns NULL from ibmvfc_get_event(). All call sites were updated to check for NULL and handle the failure or recovery path. This prevents a potential junk pointer path and kernel crash ...
