CVE-2026-5071

CVE-2026-5071 affects Zephyr RTOS SocketCAN. A NET_ASSERT-based length check in zcan_sendto_ctx() allows out-of-bounds reads in socketcan_to_can_frame() when an attacker controls the length passed to a sendto syscall and assertions are disabled in production builds. Consequences include denial-of...
