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."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/virtio/virtgpu_gem.c"],"versions":[{"version":"dc5698e80cf724770283e10414054662bdf6ccfa","lessThan":"13423a058187c2039aa8cb235c916be4477221b7","status":"affected","versionType":"git"},{"version":"dc5698e80cf724770283e10414054662bdf6ccfa","lessThan":"687be2f8b5e0e0ca9a7028f8f6413d0ed3fbb9dc","status":"affected","versionType":"git"},{"version":"dc5698e80cf724770283e10414054662bdf6ccfa","lessThan":"264ae8ac8fd625b6c118baf16c111adeee2ec632","status":"affected","versionType":"git"},{"version":"dc5698e80cf724770283e10414054662bdf6ccfa","lessThan":"e2edd2d78d2cf8446de017adec9598feefed3297","status":"affected","versionType":"git"},{"version":"dc5698e80cf724770283e10414054662bdf6ccfa","lessThan":"372e9c3d45f664a2c000427ccbf6cdc2f99b3170","status":"affected","versionType":"git"},{"version":"dc5698e80cf724770283e10414054662bdf6ccfa","lessThan":"a93dce15dfef200c346b050a2acbed516cc62706","status":"affected","versionType":"git"},{"version":"dc5698e80cf724770283e10414054662bdf6ccfa","lessThan":"f75066c79d1eec453c0d386ef8636873d1e11f2c","status":"affected","versionType":"git"},{"version":"dc5698e80cf724770283e10414054662bdf6ccfa","lessThan":"36570ef2244cc4d7563b1f0157bc0f032498638c","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/virtio/virtgpu_gem.c"],"versions":[{"version":"4.2","status":"affected"},{"version":"0","lessThan":"4.2","status":"unaffected","versionType":"semver"},{"version":"5.10.271","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.222","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.189","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.158","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.55","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.9","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.2","versionEndExcluding":"5.10.271"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.2","versionEndExcluding":"5.15.222"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.2","versionEndExcluding":"6.1.189"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.2","versionEndExcluding":"6.6.158"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.2","versionEndExcluding":"6.12.112"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.2","versionEndExcluding":"6.18.55"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.2","versionEndExcluding":"7.2.9"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.2","versionEndExcluding":"7.3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/13423a058187c2039aa8cb235c916be4477221b7"},{"url":"https://git.kernel.org/stable/c/687be2f8b5e0e0ca9a7028f8f6413d0ed3fbb9dc"},{"url":"https://git.kernel.org/stable/c/264ae8ac8fd625b6c118baf16c111adeee2ec632"},{"url":"https://git.kernel.org/stable/c/e2edd2d78d2cf8446de017adec9598feefed3297"},{"url":"https://git.kernel.org/stable/c/372e9c3d45f664a2c000427ccbf6cdc2f99b3170"},{"url":"https://git.kernel.org/stable/c/a93dce15dfef200c346b050a2acbed516cc62706"},{"url":"https://git.kernel.org/stable/c/f75066c79d1eec453c0d386ef8636873d1e11f2c"},{"url":"https://git.kernel.org/stable/c/36570ef2244cc4d7563b1f0157bc0f032498638c"}],"title":"drm/virtio: fix object leak when drm_gem_handle_create() fails","x_generator":{"engine":"bippy-1.2.0"}}}}
