7.5
High
| Vector | AV:N/AC:L/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A potential deadlock situation can occur during chip recovery in the Linux kernel, specifically in the wifi: mt76: mt7921s module. This happens when the kernel worker reset work holds a lock and waits for the kernel thread stat worker to be parked, while stat worker waits for the release of the same lock. This causes a deadlock, resulting in hung tasks messages and possible rebooting of the device. The issue is resolved by preventing the execution of stat worker during chip recovery.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
