What is CVE-2026-23995?
CVE-2026-23995 is a high-severity memory corruption vulnerability in everest-core, published on 26 Mar 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
Weakness: CWE-121
