Last modified
CVE-2022-41974 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. multipath-tools 0.7.0 through 0.9.x before 0.9.2 allows local users to obtain root access, as exploited alone or in conjunction with CVE-2022-41973. Local users able to write to UNIX domain sockets can bypass access controls and manipulate the multipath setup. EPSS estimates a 0.61% chance of exploitation in the next 30 days.
Description
multipath-tools 0.7.0 through 0.9.x before 0.9.2 allows local users to obtain root access, as exploited alone or in conjunction with CVE-2022-41973. Local users able to write to UNIX domain sockets can bypass access controls and manipulate the multipath setup. This can lead to local privilege escalation to root. This occurs because an attacker can repeat a keyword, which is mishandled because arithmetic ADD is used instead of bitwise OR.
