{"cve":"CVE-2026-98609","nvd":{"published":"2026-10-18T16:17:13.677","modified":"2026-10-19T10:19:22.927","status":"Received","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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/13423a058187c2039aa8cb235c916be4477221b7","https://git.kernel.org/stable/c/264ae8ac8fd625b6c118baf16c111adeee2ec632","https://git.kernel.org/stable/c/36570ef2244cc4d7563b1f0157bc0f032498638c","https://git.kernel.org/stable/c/372e9c3d45f664a2c000427ccbf6cdc2f99b3170","https://git.kernel.org/stable/c/687be2f8b5e0e0ca9a7028f8f6413d0ed3fbb9dc"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-98609","score":0.00177,"percentile":0.07173,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
