Description

A flaw was found in the Linux kernel's `rtw88` and `rtw8822b` WiFi drivers. A local user can trigger a kernel warning by invoking the `rtw8822b_set_antenna()` function when the WiFi chip is powered off. This improper state handling leads to the driver attempting to read radio frequency (RF) registers, resulting in unexpected values and system instability. This could potentially lead to a denial of service.
