Description

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. Addresses-Coverity-ID: 1598775 ("Out-of-bounds read")
