Descriptions

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: Add mutex lock in control vblank irq Add a mutex lock to control vblank irq to synchronize vblank
enable/disable operations happening from different threads to prevent
race conditions while registering/unregistering the vblank irq callback. v4: -Removed vblank_ctl_lock from dpu_encoder_virt, so it is only a parameter of dpu_encoder_phys. -Switch from atomic refcnt to a simple int counter as mutex has now been added
v3: Mistakenly did not change wording in last version. It is done now.
v2: Slightly changed wording of commit message Patchwork: https://patchwork.freedesktop.org/patch/571854/

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/msm/dpu: agregue un bloqueo mutex en el control vblank irq. Agregue un bloqueo mutex para controlar vblank irq para sincronizar las operaciones de activación/desactivación de vblank que ocurren desde diferentes subprocesos para evitar condiciones de ejecución durante el registro. /anular el registro de la devolución de llamada vblank irq. v4: -Se eliminó vblank_ctl_lock de dpu_encoder_virt, por lo que es solo un parámetro de dpu_encoder_phys. -Cambiar de refcnt atómico a un contador int simple ya que ahora se ha agregado mutex v3: por error no cambió la redacción en la última versión. Ya está hecho. v2: redacción ligeramente modificada del mensaje de confirmación Patchwork: https://patchwork.freedesktop.org/patch/571854/
