CVE-2022-50053 is a deadlock vulnerability in the Linux kernel Intel Adaptive Virtual Function (iavf) Ethernet driver. In the reset-task error path, iavf_reset_task could call iavf_close after a failed virtual-function reset. This can invoke napi_disable twice, deadlocking the driver. Rapid VF resets that cause VF mailbox initialization to fail can exercise the faulty path; subsequent VF removal may block because iavf_remove waits for crit_lock held by iavf_close. The fix replaces this cleanup path with iavf_disable_vf, allowing invalid remaining resources to be safely cleaned up.
