CVE-2026-53101

In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7921: fix potential deadlock in mt7921rocabort_sync

rocabortsync() can deadlock with rocwork(). rocwork() holds dev->mt76.mutex, while cancelworksync() waits for roc_work() to finish. If the caller already owns the same mutex, both sides block and no progress is possible.

This deadlock can occur during station removal when mt76stastate() -> mt76staremove() -> mt7921macstaremove() -> mt7921rocabortsync() invokes cancelworksync() while roc_work() is still running and holding dev->mt76.mutex.

This avoids the mutex deadlock and preserves exactly-once work ownership.
