CVE-2025-35968

Protection mechanism failure in the UEFI firmware for the Slim Bootloader within firmware may allow an escalation of privilege. Startup code and smm adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Summary		(es) Falla del mecanismo de protección en el firmware UEFI para el Slim Bootloader dentro del firmware puede permitir una escalada de privilegios. Código de inicio y adversario SMM con un usuario privilegiado combinado con un ataque de alta complejidad puede habilitar la escalada de privilegios. Este resultado puede ocurrir potencialmente a través de acceso local cuando los requisitos de ataque están presentes sin conocimiento interno especial y no requiere interacción del usuario. La potencial vulnerabilidad puede impactar la confidencialidad (alta), integridad (alta) y disponibilidad (alta) del sistema vulnerable, resultando en impactos posteriores en la confidencialidad (ninguno), integridad (ninguno) y disponibilidad (ninguno) del sistema.
