  "description": "In the Linux kernel, the following vulnerability has been resolved:  iavf: fix PTP use-after-free during reset  Commit 7c01dbfc8a1c5f (\u0022iavf: periodically cache PHC time\u0022) introduced a worker to cache PHC time, but failed to stop it during reset or disable.  This creates a race condition where \u0060iavf_reset_task()\u0060 or \u0060iavf_disable_vf()\u0060 free adapter resources (AQ) while the worker is still running. If the worker triggers \u0060iavf_queue_ptp_cmd()\u0060 during teardown, it accesses freed memory/locks, leading to a crash.  Fix this by calling \u0060iavf_ptp_release()\u0060 before tearing down the adapter. This ensures \u0060ptp_clock_unregister()\u0060 synchronously cancels the worker and cleans up the chardev before the backing resources are destroyed.",
