CVE-2026-37532

Memory disclosure and crash via oversized ISO-TP frame

Published May 1, 2026 · Updated May 1, 2026

Heap buffer over-read in AGL agl-service-can-low-level 17.1.12 and earlier allows remote attackers to read memory or crash the service. A crafted Single Frame length nibble above seven makes isotp_continue_receive copy up to 15 bytes from a seven-byte payload region with memcpy. Reachability requires CAN-bus access or access to the AGL CAN service API; the published impact is limited to memory disclosure and service interruption.
