CVE-2024-42125

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.
