Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: sar: drop lockdep assertion in rtw89_set_sar_from_acpi
The following assertion is triggered on the rtw89 driver startup. It looks meaningless to hold wiphy lock on the early init stage so drop the assertion.
