PatchTheCVECVE-2026-37530: AGL agl-service-can-low-level thru 17.1.12 contains a stack buffer overflow in the uds-c library
CVE-2026-37530 is a high-severity flaw (CVSS 7.5) affecting automotive grade linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
AGL agl-service-can-low-level thru 17.1.12 contains a stack buffer overflow in the uds-c library. The send_diagnostic_request function in uds.c allocates a 6-byte stack buffer (MAX_DIAGNOSTIC_PAYLOAD_SIZE=6) but copies up to 7 bytes (MAX_UDS_REQUEST_PAYLOAD_LENGTH=7) via memcpy at an offset of 1+pid_length (2-3 bytes), resulting in 1-4 bytes of controlled stack overflow. The payload_length field (uint8_t) has no bounds check against the destinati
