In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
drm: Fix drm_pending_vblank_event leak in error path for out_fence_ptr<\/p>\n
When an out_fence_ptr is provided but DRM_MODE_PAGE_FLIP_EVENT is not
\nset, a drm_pending_vblank_event will be allocated. If later, there is an
\nallocation failure or another failure at setup_out_fence(), that event
\nwill not have base.fence set and it will not be released at
\ncomplete_signaling().<\/p>\n
Release the event and set crtc_state->event to NULL just like in the
\nDRM_MODE_PAGE_FLIP_EVENT case when there is a failure at
\ndrm_event_reserve_init(). That is, prepare_signaling() releases the
\nevent and there is nothing to be done at complete_signaling(). Use
\ndrm_event_cancel_free() as that will also undo drm_event_reserve_init()
\nin case it has been called.<\/p>\n","protected":false},"excerpt":{"rendered":"
