In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: fw: scan offload prohibit all 6 GHz channel if no 6 GHz sband
We have some policy via BIOS to block uses of 6 GHz. In this case, 6 GHz
sband will be NULL even if it is WiFi 7 chip. So, add NULL handling here
to avoid crash.

kernel: wifi: rtw89: fw: scan offload prohibit all 6 GHz channel if no 6 GHz sband
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: fw: scan offload prohibit all 6 GHz channel if no 6 GHz sband
We have some policy via BIOS to block uses of 6 GHz. In this case, 6 GHz
sband will be NULL even if it is WiFi 7 chip. So, add NULL handling here
to avoid crash.
A vulnerability was found in the Linux kernel's rtw89 driver function rtw89_scan_get_6g_disabled_chan() caused by its handling of 6 GHz band channels during scans. A lack of proper sband checks can lead to a situation where the sband is not available due to device limitations/restrictions set by the BIOS and this leads to a NULL pointer dereference. This can lead to system instability or crashes.
