Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/etnaviv: comprobar mapeo cosechado en etnaviv_iommu_unmap_gem Cuando el mapeo ya fue cosechado, anular el mapeo debe ser una operación nula, ya que de lo contrario intentaríamos eliminar el mapeo dos veces, corrompiendo las estructuras de datos involucradas.
