      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\niavf: fix PTP use-after-free during reset\n\nCommit 7c01dbfc8a1c5f (\"iavf: periodically cache PHC time\") introduced a\nworker to cache PHC time, but failed to stop it during reset or disable.\n\nThis creates a race condition where `iavf_reset_task()` or\n`iavf_disable_vf()` free adapter resources (AQ) while the worker is still\nrunning. If the worker triggers `iavf_queue_ptp_cmd()` during teardown, it\naccesses freed memory/locks, leading to a crash.\n\nFix this by calling `iavf_ptp_release()` before tearing down the adapter.\nThis ensures `ptp_clock_unregister()` synchronously cancels the worker and\ncleans up the chardev before the backing resources are destroyed.",
