Vulnerability from fkie_nvd - Published: 2024-07-12 13:15 - Updated: 2025-11-03 22:17
Severity ?
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7921s: fix potential hung tasks during chip recovery
During chip recovery (e.g. chip reset), there is a possible situation that
kernel worker reset_work is holding the lock and waiting for kernel thread
stat_worker to be parked, while stat_worker is waiting for the release of
the same lock.
It causes a deadlock resulting in the dumping of hung tasks messages and
possible rebooting of the device.
This patch prevents the execution of stat_worker during the chip recovery.
