Summary
A vulnerability has been identified in the Linux kernel related to the wifi: mt76: mt7921 component, concerning a potential clc buffer length underflow. This underflow may lead to an almost infinite loop or an invalid power setting, resulting in driver initialization failure.
Risk Assessment
This vulnerability can lead to driver failure, impacting the stability and availability of network services within the organization. If exploited, it could cause significant disruptions to system operations.
Recommendation
It is recommended to update the Linux kernel to the latest version where this vulnerability has been fixed. Additionally, monitor systems for unauthorized changes in network configuration.

Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: fix a potential clc buffer length underflow The buf_len is used to limit the iterations for retrieving the country power setting and may underflow under certain conditions due to changes in the power table in CLC. This underflow leads to an almost infinite loop or an invalid power setting resulting in driver initialization failure.
