When a cgroup is being destroyed, cgroup_rstat_flush() is only called at css_release_work_fn(), which is called when the blkcg reference count reaches 0. This circular dependency will prevent blkcg and some blkgs from being freed after they are made offline. This issue may allow an attacker with a local access to cause system instability, such as an out of memory error.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-668","CWE-402"],"references":["https://access.redhat.com/errata/RHSA-2023:6583","https://access.redhat.com/errata/RHSA-2023:7077","https://access.redhat.com/errata/RHSA-2023:7370","https://access.redhat.com/security/cve/CVE-2024-0443","https://bugzilla.redhat.com/show_bug.cgi?id=2257968"],"products":["fedoraproject:fedora","linux:linux_kernel","redhat:enterprise_linux"],"source":"nvd","synced_at":"2026-10-26T18:42:44.273634044+00:00"},"epss":{"cve":"CVE-2024-0443","score":0.00249,"percentile":0.1613,"date":"2026-10-26"},"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).
