CVE-2022-41973

device-mapper-multipath: multipathd: insecure handling of files in /dev/shm leading to symlink attack

Published Oct 29, 2022 CVSS 3.1 · 7.8 High EPSS < 1% KEV · Not listed
Description
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.
