{"id":"CVE-2026-98609","published":"2026-10-18T16:17:13.677","lastModified":"2026-10-19T10:19:22.927","description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/virtio: fix object leak when drm_gem_handle_create() fails\n\nvirtio_gpu_gem_create() owns the reference taken by\nvirtio_gpu_object_create(). 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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/13423a058187c2039aa8cb235c916be4477221b7","tags":[]},{"url":"https://git.kernel.org/stable/c/264ae8ac8fd625b6c118baf16c111adeee2ec632","tags":[]},{"url":"https://git.kernel.org/stable/c/36570ef2244cc4d7563b1f0157bc0f032498638c","tags":[]},{"url":"https://git.kernel.org/stable/c/372e9c3d45f664a2c000427ccbf6cdc2f99b3170","tags":[]},{"url":"https://git.kernel.org/stable/c/687be2f8b5e0e0ca9a7028f8f6413d0ed3fbb9dc","tags":[]},{"url":"https://git.kernel.org/stable/c/a93dce15dfef200c346b050a2acbed516cc62706","tags":[]},{"url":"https://git.kernel.org/stable/c/e2edd2d78d2cf8446de017adec9598feefed3297","tags":[]},{"url":"https://git.kernel.org/stable/c/f75066c79d1eec453c0d386ef8636873d1e11f2c","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
