Details

EVerest is an EV charging software stack. Prior to version 2026.02.0, stack-based buffer overflow in CAN interface initialization: passing an interface name longer than IFNAMSIZ (16) to CAN open routines overflows ifreq.ifr_name, corrupting adjacent stack data and enabling potential code execution. A malicious or misconfigured interface name can trigger this before any privilege checks. Version 2026.02.0 contains a patch.
