Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mt76: mt7921: fix crash when startup fails.<br /> <br /> If the nic fails to start, it is possible that the<br /> reset_work has already been scheduled. Ensure the<br /> work item is canceled so we do not have use-after-free<br /> crash in case cleanup is called before the work item<br /> is executed.<br /> <br /> This fixes crash on my x86_64 apu2 when mt7921k radio<br /> fails to work. Radio still fails, but OS does not<br /> crash.
