CVE-2025-31944

Race condition for some TDX Module before version tdx1.5 within Ring 0: Hypervisor may allow a denial of service. Authorized adversary with a privileged user combined with a high complexity attack may enable denial of service. 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 (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (low) impacts.

Summary		(es) Condición de carrera para algunos módulos TDX antes de la versión tdx1.5 dentro del Anillo 0: El hipervisor puede permitir una denegación de servicio. Adversario autorizado con un usuario privilegiado combinado con un ataque de alta complejidad puede habilitar la denegación de servicio. 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 (ninguna), integridad (ninguna) y disponibilidad (alta) del sistema vulnerable, resultando en impactos subsiguientes en la confidencialidad (ninguna), integridad (ninguna) y disponibilidad (baja) del sistema.
