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() ->\nmt7925_mac_sta_remove_link() -> mt7925_mac_link_sta_remove() ->\nmt7925_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.\n\n## Affected\n\n- `Linux >= 45064d19fd3af6aeb0887b35b5564927980cf150 < 253cfc33d95ce4a30fd2eca0ff0138603c6c2fcc`\n- `Linux >= 45064d19fd3af6aeb0887b35b5564927980cf150 < 153bcba36c87a1ba555b57b6c49028d5812f895b`\n- `Linux >= 45064d19fd3af6aeb0887b35b5564927980cf150 < 2d8e0053bca29143ace51e08c980ff076844a4b0`\n- `Linux >= 45064d19fd3af6aeb0887b35b5564927980cf150 < dd08ca3f092f4185ece69ce2a835c23198b1628a`\n- `Linux 978d1756b3ae1b857826eb7ed8181f3c5180dce9`\n- `Linux >= 6.11.2 < 6.12`\n- `Linux 6.12`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
