CVE-2026-73522
Description
COVESA Open1722 through 0.9.2 contains a stack buffer overflow vulnerability that allows unauthenticated remote attackers to write past the end of a fixed 15-slot stack array by sending a crafted UDP datagram containing more than 15 ACF-CAN messages. The avtp_to_can() function increments its write index without bounding it against the caller-supplied array size, and because the listener accepts datagrams from any sender matching a hardcoded unauthenticated stream ID transmitted in plaintext, attackers can corrupt adjacent stack memory to achieve arbitrary code execution or denial of service.
