{"id":"MGASA-2025-0188","summary":"Updated udisks2 & libblockdev packages fix security vulnerabilities","details":"A Local Privilege Escalation (LPE) vulnerability was found in\nlibblockdev. Generally, the \"allow_active\" setting in Polkit permits a\nphysically present user to take certain actions based on the session\ntype. Due to the way libblockdev interacts with the udisks daemon, an\n\"allow_active\" user on a system may be able escalate to full root\nprivileges on the target host. Normally, udisks mounts user-provided\nfilesystem images with security flags like nosuid and nodev to prevent\nprivilege escalation. However, a local attacker can create a specially\ncrafted XFS image containing a SUID-root shell, then trick udisks into\nresizing it. This mounts their malicious filesystem with root\nprivileges, allowing them to execute their SUID-root shell and gain\ncomplete control of the system.\n","modified":"2026-04-16T04:44:25.472443161Z","published":"2025-06-24T20:11:57Z","upstream":["CVE-2025-6019"],"references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2025-0188.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=34380"},{"type":"WEB","url":"https://www.openwall.com/lists/oss-security/2025/06/17/4"}],"affected":[{"package":{"name":"udisks2","ecosystem":"Mageia:9","purl":"pkg:rpm/mageia/udisks2?arch=source&distro=mageia-9"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.10.1-1.1.mga9"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2025-0188.json"}},{"package":{"name":"libblockdev","ecosystem":"Mageia:9","purl":"pkg:rpm/mageia/libblockdev?arch=source&distro=mageia-9"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.3.1-1.mga9"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2025-0188.json"}}],"schema_version":"1.7.5","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
