CVE-2022-49129 Information

Description

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.
