HIGH

Linux Kernel 4.16-5.15.33, 5.12.0-5.15.33, 5.16.0-5.16.19, 5.17.0-5.17.2 - Use-After-Free in mt7921 Reset Work

Title source: llm
STIX 2.1

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.
