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