      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm: Fix drm_crtc_commit leak if signaled when PAGE_FLIP_EVENT is used\n\nCommit 1c6ceeee6ebb (\"drm/atomic: Fix memleak on ERESTARTSYS during\nnon-blocking commits\") fixed a very similar issue when the event was\nallocated by drm_atomic_helper_setup_commit() itself.\n\nHowever, if the event is allocated in prepare_signaling(), it will also be\nset to NULL in complete_signaling(), which prevents drm_crtc_commit from\nbeing put in __drm_atomic_helper_crtc_destroy_state().\n\nDropping the reference when the event is set to NULL at\ncomplete_signaling() fixes the leak.\n\nThe leak can be reproduced by sending a signal to the thread using\nDRM_MODE_PAGE_FLIP_EVENT and using a sw_sync fence to cause the atomic\nioctl to block at drm_atomic_helper_wait_for_fences(). It happened both\nwith amdgpu and vkms.",
