Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/vrr: establezca la propiedad con capacidad de VRR solo si está conectada al conector. La propiedad con capacidad de VRR no está conectada de manera predeterminada al conector. Se conecta solo si se admite VRR. Entonces, si el controlador intenta llamar a la función drm core set prop sin que esté adjunta, eso causa una desreferencia NULL.
