{"id":"CVE-2026-111581","published":"2026-10-16T16:17:04.680","lastModified":"2026-10-16T19:23:18.623","description":"A flaw was found in libblockdev. The bd_fs_ntfs_set_label() and bd_fs_vfat_set_label() functions pass caller-supplied label values as bare positional arguments to the ntfslabel and fatlabel utilities without end-of-options separators or input validation for values beginning with a dash. This allows a label starting with '-' to be interpreted as a command-line flag by the spawned tool, potentially bypassing safety checks or causing unintended operations. This is reachable by unprivileged local users through the udisks2 Filesystem.SetLabel() D-Bus method without administrator authentication.","cvssScore":3.3,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","cwes":["CWE-88"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-111581","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2554104","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
