  2. Vulnerabilities (CVE)
  3. CVE-2022-50079
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Check correct bounds for stream encoder instances for DCN303 [Why & How] eng_id for DCN303 cannot be more than 1, since we have only two instances of stream encoders. Check the correct boundary condition for engine ID for DCN303 prevent the potential out of bounds access.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Verificar los límites correctos para las instancias del codificador de flujo para DCN303 [Por qué y cómo] El valor eng_id para DCN303 no puede ser mayor que 1, ya que solo tenemos dos instancias de codificadores de flujo. Verificar la condición de límite correcta para el ID del motor para DCN303 previene el posible acceso fuera de los límites.
