This is the contract of this function.\n\nHowever, there is a location within the driver where both\npmac_id_valid == false and pmac_id == NULL are being passed. This could\nresult in dereferencing a NULL pointer.\n\nTo resolve this issue, it is necessary to pass the address of a stub\nvariable to the function.\n\n## Affected\n\n- `Linux >= 95046b927a54f461766f83a212c6a93bc5fd2e67 < 4cba480c9b9a3861a515262225cb53a1f5978344`\n- `Linux >= 95046b927a54f461766f83a212c6a93bc5fd2e67 < 92c6dc181a18e6e0ddb872ed35cb48a9274829e4`\n- `Linux >= 95046b927a54f461766f83a212c6a93bc5fd2e67 < 6c3e00888dbec887125a08b51a705b9b163fcdd1`\n- `Linux >= 95046b927a54f461766f83a212c6a93bc5fd2e67 < e206fb415db36bad52bb90c08d46ce71ffbe8a80`\n- `Linux >= 95046b927a54f461766f83a212c6a93bc5fd2e67 < 47ffb4dcffe336f4a7bd0f3284be7aadc6484698`\n- `Linux >= 95046b927a54f461766f83a212c6a93bc5fd2e67 < 31410a01a86bcb98c798d01061abf1f789c4f75a`\n- `Linux >= 95046b927a54f461766f83a212c6a93bc5fd2e67 < 8215794403d264739cc676668087512950b2ff31`\n- `Linux 3.12`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
