It occurs in the storagePoolLookupByTargetPath function where a locked virStoragePoolObj object is not properly released on ACL permission failure. Clients connecting to the read-write socket with limited ACL permissions could use this flaw to acquire the lock and prevent other users from accessing storage pool/volume APIs, resulting in a denial of service condition. The highest threat from this vulnerability is to system availability."}],"affected":[{"vendor":"n/a","product":"libvirt","versions":[{"version":"Fixedin - libvert v7.6.0-rc1 and above","status":"affected"}]}],"references":[{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=1986094"},{"url":"https://libvirt.org/git/?p=libvirt.git%3Ba=commit%3Bh=447f69dec47e1b0bd15ecd7cd49a9fd3b050fb87"},{"url":"https://gitlab.com/libvirt/libvirt/-/commit/447f69dec47e1b0bd15ecd7cd49a9fd3b050fb87"},{"url":"https://security.netapp.com/advisory/ntap-20220331-0005/"},{"name":"GLSA-202210-06","tags":["vendor-advisory"],"url":"https://security.gentoo.org/glsa/202210-06"},{"url":"https://lists.debian.org/debian-lts-announce/2024/04/msg00000.html"}],"problemTypes":[{"descriptions":[{"type":"CWE","lang":"en","description":"CWE-667  (improper Locking)","cweId":"CWE-667"}]}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T17:01:08.343Z"},"title":"CVE Program Container","references":[{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=1986094","tags":["x_transferred"]},{"url":"https://libvirt.org/git/?p=libvirt.git%3Ba=commit%3Bh=447f69dec47e1b0bd15ecd7cd49a9fd3b050fb87","tags":["x_transferred"]},{"url":"https://gitlab.com/libvirt/libvirt/-/commit/447f69dec47e1b0bd15ecd7cd49a9fd3b050fb87","tags":["x_transferred"]},{"url":"https://security.netapp.com/advisory/ntap-20220331-0005/","tags":["x_transferred"]},{"name":"GLSA-202210-06","tags":["vendor-advisory","x_transferred"],"url":"https://security.gentoo.org/glsa/202210-06"},{"url":"https://lists.debian.org/debian-lts-announce/2024/04/msg00000.html","tags":["x_transferred"]}]}]}}
