Important: device-mapper-multipath security update (Amazon Linux 2)

Published Dec 1, 2022 · Updated Dec 6, 2022

Summary

Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2022-41974: 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.
