CVE-2024-50003

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix system hang while resume with TBT monitor [Why] Connected with a Thunderbolt monitor and do the suspend and the system may hang while resume. The TBT monitor HPD will be triggered during the resume procedure and call the drm_client_modeset_probe() while struct drm_connector connector->dev->master is NULL. It will mess up the pipe topology after resume. [How] Skip the TBT monitor HPD during the resume procedure because we currently will probe the connectors after resume by default. (cherry picked from commit 453f86a26945207a16b8f66aaed5962dc2b95b85)

Summary		(es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Se soluciona el bloqueo del sistema durante la reanudación con el monitor TBT [Por qué] Conectado con un monitor Thunderbolt y realizando la suspensión, el sistema puede bloquearse durante la reanudación. El HPD del monitor TBT se activará durante el procedimiento de reanudación y llamará a drm_client_modeset_probe() mientras struct drm_connector connector->dev->master sea NULL. Esto arruinará la topología de la tubería después de la reanudación. [Cómo] Omitir el HPD del monitor TBT durante el procedimiento de reanudación porque actualmente sondearemos los conectores después de la reanudación de forma predeterminada.
