CVE-2022-41973

HIGH

multipath-tools 0.7.7-0.9.1 - Local Privilege Escalation via Symlink Attack

Title source: llm
STIX 2.1

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.
