CVE-2026-53101

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A potential deadlock exists in the mt7921 roc abort sync() function within the mt76 wireless driver. The issue occurs when roc abort sync() calls cancel work sync(), which waits for roc work() to complete. Because roc work() holds the dev->mt76.mutex lock, a deadlock occurs if the caller already owns that same mutex. This scenario typically happens during station removal through the sequence of functions mt76 sta state() -> mt76 sta remove() -> mt7921 mac sta remove() -> mt7921 roc abort sync().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
