Description OSIDB Bzimport 2024-10-21 13:05:35 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: rtw89: remove unused C2H event ID RTW89_MAC_C2H_FUNC_READ_WOW_CAM to prevent out-of-bounds reading

The handler of firmware C2H event RTW89_MAC_C2H_FUNC_READ_WOW_CAM isn't
implemented, but driver expects number of handlers is
NUM_OF_RTW89_MAC_C2H_FUNC_WOW causing out-of-bounds access. Fix it by
removing ID.
