Vulnerability Title
EVerest has stack buffer overflow in ifreq.ifr_name when interface name exceeds IFNAMSIZ
Source: CVE Program / CVE List V5
Vulnerability Description
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.
