  3. CVE-2024-46837
In the Linux kernel, the following vulnerability has been resolved: drm/panthor: Restrict high priorities on group_create We were allowing any users to create a high priority group without any permission checks. As a result, this was allowing possible denial of service. We now only allow the DRM master or users with the CAP_SYS_NICE capability to set higher priorities than PANTHOR_GROUP_PRIORITY_MEDIUM. As the sole user of that uAPI lives in Mesa and hardcode a value of MEDIUM [1], this should be safe to do. Additionally, as those checks are performed at the ioctl level, panthor_group_create now only check for priority level validity.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/panthor: Restringir altas prioridades en group_create Permitíamos que cualquier usuario creara un grupo de alta prioridad sin ninguna verificación de permisos. Como resultado, esto permitía una posible denegación de servicio. Ahora solo permitimos que el maestro DRM o los usuarios con la capacidad CAP_SYS_NICE establezcan prioridades más altas que PANTHOR_GROUP_PRIORITY_MEDIUM. Como el único usuario de esa uAPI vive en Mesa y codifica un valor de MEDIUM [1], esto debería ser seguro de hacer. Además, como esas verificaciones se realizan en el nivel ioctl, panthor_group_create ahora solo verifica la validez del nivel de prioridad.
