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.
