Description
A flaw was found in the rtw89 Wi-Fi driver within the Linux kernel. This vulnerability occurs because an unused firmware event identifier, RTW89_MAC_C2H_FUNC_READ_WOW_CAM, does not have a corresponding handler, yet the driver attempts to access one. This mismatch can lead to an out-of-bounds read, potentially allowing an attacker to access sensitive information from memory.
