This vulnerability occurs within the rtw_BIP_verify() function, where a variable is not fully initialized, leaving two bytes with unpredictable values. This uninitialized data can lead to unpredictable system behavior, potentially resulting in a denial of service (DoS) or information disclosure." ],
