Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: Fix alignment fault in rtw_core_enable_beacon()
rtw_core_enable_beacon() reads 4 bytes from an address that is not a
multiple of 4. This results in a crash on some systems.
Do 1 byte reads/writes instead.
Unable to handle kernel paging request at virtual address ffff8000827e0522
