  3. CVE-2023-52634
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix disable_otg_wa logic [Why] When switching to another HDMI mode, we are unnecesarilly disabling/enabling FIFO causing both HPO and DIG registers to be set at the same time when only HPO is supposed to be set. This can lead to a system hang the next time we change refresh rates as there are cases when we don't disable OTG/FIFO but FIFO is enabled when it isn't supposed to be. [How] Removing the enable/disable FIFO entirely.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: corrige la lógica enable_otg_wa [Por qué] Cuando cambiamos a otro modo HDMI, deshabilitamos/habilitamos FIFO innecesariamente, lo que hace que los registros HPO y DIG se configuren al mismo tiempo. momento en el que se supone que sólo se debe configurar HPO. Esto puede provocar que el sistema se cuelgue la próxima vez que cambiemos las frecuencias de actualización, ya que hay casos en los que no deshabilitamos OTG/FIFO pero FIFO está habilitado cuando no debería estarlo. [Cómo] Eliminar completamente la activación/desactivación de FIFO.
