{"id":"UBUNTU-CVE-2022-41973","details":"multipath-tools 0.7.7 through 0.9.x before 0.9.2 allows local users to obtain root access, as exploited in conjunction with CVE-2022-41974. Local users able to access /dev/shm can change symlinks in multipathd due to incorrect symlink handling, which could lead to controlled file writes outside of the /dev/shm directory. This could be used indirectly for local privilege escalation to root.","modified":"2026-02-04T02:23:38.324698Z","published":"2022-10-24T15:00:00Z","related":["USN-5731-1"],"upstream":["CVE-2022-41973"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-41973"},{"type":"REPORT","url":"https://www.qualys.com/2022/10/24/leeloo-multipath/leeloo-multipath.txt"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-5731-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-41973"}],"affected":[{"package":{"name":"multipath-tools","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/multipath-tools@0.8.3-1ubuntu2.1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.8.3-1ubuntu2.1"}]}],"versions":["0.7.9-3ubuntu6","0.7.9-3ubuntu7","0.8.3-1ubuntu1","0.8.3-1ubuntu2"],"ecosystem_specific":{"binaries":[{"binary_name":"kpartx","binary_version":"0.8.3-1ubuntu2.1"},{"binary_name":"kpartx-boot","binary_version":"0.8.3-1ubuntu2.1"},{"binary_name":"multipath-tools","binary_version":"0.8.3-1ubuntu2.1"},{"binary_name":"multipath-tools-boot","binary_version":"0.8.3-1ubuntu2.1"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-41973.json"}},{"package":{"name":"multipath-tools","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/multipath-tools@0.8.8-1ubuntu1.22.04.1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.8.8-1ubuntu1.22.04.1"}]}],"versions":["0.8.5-2ubuntu2","0.8.5-2ubuntu3","0.8.8-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"kpartx","binary_version":"0.8.8-1ubuntu1.22.04.1"},{"binary_name":"kpartx-boot","binary_version":"0.8.8-1ubuntu1.22.04.1"},{"binary_name":"multipath-tools","binary_version":"0.8.8-1ubuntu1.22.04.1"},{"binary_name":"multipath-tools-boot","binary_version":"0.8.8-1ubuntu1.22.04.1"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-41973.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
