CVE-2022-49644
Estado: ModificadaMedia (5.5)—
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)
