Move disabling the elevator and freeing the scheduler tags\nto the end of del_gendisk instead of doing that work in disk_release and\nblk_cleanup_queue to avoid a use after free on q->tag_set from\ndisk_release as the tag_set might not be alive at that point.\n\nMove the blk_qos_exit call as well, as it just depends on the elevator\nexit and would be the only reason to keep the not exactly cheap queue\nfreeze in disk_release.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-416"],"references":["https://git.kernel.org/stable/c/50e34d78815e474d410f342fbe783b18192ca518","https://git.kernel.org/stable/c/f28699fafc047ec33299da01e928c3a0073c5cc6"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49694","score":0.00249,"percentile":0.16297,"date":"2026-10-31"},"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).
