EVerest is an EV charging software stack. Prior to version 2026.02.0, an off-by-one check in IsoMux certificate filename handling causes a stack-based buffer overflow when a filename length equals MAX_FILE_NAME_LENGTH (100). A crafted filename in the certificate directory can overflow file_names[idx], corrupting stack state and enabling potential code execution. Version 2026.02.0 contains a patch.
