CVE-2025-27940

Out-of-bounds read for some TDX Module before version tdx1.5 within Ring 0: Hypervisor may allow an information disclosure. Software side channel adversary with a privileged user combined with a high complexity attack may enable data exposure. 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 (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

Summary		(es) Lectura fuera de límites para algún Módulo TDX anterior a la versión tdx1.5 dentro del Anillo 0: El hipervisor puede permitir una revelación de información. Un adversario de canal lateral de software con un usuario privilegiado combinado con un ataque de alta complejidad puede permitir la exposición de datos. 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 vulnerabilidad potencial puede impactar la confidencialidad (alta), integridad (ninguna) y disponibilidad (ninguna) del sistema vulnerable, resultando en impactos subsiguientes en la confidencialidad (ninguna), integridad (ninguna) y disponibilidad (ninguna) del sistema.
