Detailsinfo

A vulnerability was found in EVerest everest-core. It has been declared as critical. This vulnerability affects the function ifr_name of the component CAN Interface. The manipulation with an unknown input leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is CWE-121.

As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.
