On the drm_gem_handle_create() error path it\ncalls drm_gem_object_release() instead of dropping that reference.\n\ndrm_gem_object_release() is the inverse of drm_gem_object_init() and does\nnot touch the reference count or call obj->funcs->free(), so it is only\ncorrect as the last step of a destructor, as in\nvirtio_gpu_cleanup_object(). Using it here leaves the bo at refcount 1\nwith no remaining reference, so virtio_gpu_free_object() never runs and\nthe shmem pages, sg table and virtio_gpu_object are leaked. Since\nvirtio_gpu_object_create() has already set bo->created,\nVIRTIO_GPU_CMD_RESOURCE_UNREF is not queued either, leaking the host-side\nresource and the resource id.\n\ndrm_gem_handle_create_tail() drops the handle reference on all of its\ninternal error paths, so the caller only has to drop its own. Use\ndrm_gem_object_put(), matching the success path below.\n\n## Affected\n\n- `Linux >= dc5698e80cf724770283e10414054662bdf6ccfa < 13423a058187c2039aa8cb235c916be4477221b7`\n- `Linux >= dc5698e80cf724770283e10414054662bdf6ccfa < 687be2f8b5e0e0ca9a7028f8f6413d0ed3fbb9dc`\n- `Linux >= dc5698e80cf724770283e10414054662bdf6ccfa < 264ae8ac8fd625b6c118baf16c111adeee2ec632`\n- `Linux >= dc5698e80cf724770283e10414054662bdf6ccfa < e2edd2d78d2cf8446de017adec9598feefed3297`\n- `Linux >= dc5698e80cf724770283e10414054662bdf6ccfa < 372e9c3d45f664a2c000427ccbf6cdc2f99b3170`\n- `Linux >= dc5698e80cf724770283e10414054662bdf6ccfa < a93dce15dfef200c346b050a2acbed516cc62706`\n- `Linux >= dc5698e80cf724770283e10414054662bdf6ccfa < f75066c79d1eec453c0d386ef8636873d1e11f2c`\n- `Linux >= dc5698e80cf724770283e10414054662bdf6ccfa < 36570ef2244cc4d7563b1f0157bc0f032498638c`\n- `Linux 4.2`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
