In the Linux kernel, the following vulnerability has been resolved: drm/i915: fix a possible refcount leak in intel_dp_add_mst_connector() If drm_connector_init fails, intel_connector_free will be called to take care of proper free. So it is necessary to drop the refcount of port before intel_connector_free. (cherry picked from commit cea9ed611e85d36a05db52b6457bf584b7d969e2)

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/i915: se corrige una posible pérdida de recuento de referencias en intel_dp_add_mst_connector(). Si drm_connector_init falla, se llamará a intel_connector_free para encargarse de la liberación adecuada. Por lo tanto, es necesario eliminar el recuento de referencias del puerto antes de intel_connector_free. (seleccionado de el commit cea9ed611e85d36a05db52b6457bf584b7d969e2)
