CVE-2026-22593

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.

Summary		(es) EVerest es una pila de software de carga de VE. Antes de la versión 2026.02.0, una comprobación de off-by-one en el manejo de nombres de archivo de certificados IsoMux causa un desbordamiento de búfer basado en pila cuando la longitud de un nombre de archivo es igual a 'MAX_FILE_NAME_LENGTH' (100). Un nombre de archivo manipulado en el directorio de certificados puede desbordar 'file_names[idx]', corrompiendo el estado de la pila y permitiendo la posible ejecución de código. La versión 2026.02.0 contiene un parche.
