Last modified
CVE-2022-41973 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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. EPSS estimates a 0.66% chance of exploitation in the next 30 days.
