  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7921: fix potential deadlock in mt7921_roc_abort_sync\n\nroc_abort_sync() can deadlock with roc_work(). roc_work() holds\ndev->mt76.mutex, while cancel_work_sync() waits for roc_work()\nto finish. If the caller already owns the same mutex, both\nsides block and no progress is possible.\n\nThis deadlock can occur during station removal when\nmt76_sta_state() -> mt76_sta_remove() -> mt7921_mac_sta_remove() ->\nmt7921_roc_abort_sync() invokes cancel_work_sync() while\nroc_work() is still running and holding dev->mt76.mutex.\n\nThis avoids the mutex deadlock and preserves exactly-once\nwork ownership.",
