Amazon Linux 2 : device-mapper-multipath (ALAS-2022-1883)

high Nessus Plugin ID 168434


The remote Amazon Linux 2 host is missing a security update.


The version of device-mapper-multipath installed on the remote host is prior to 0.4.9-136. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2022-1883 advisory.

- 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. (CVE-2022-41974)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Run 'yum update device-mapper-multipath' to update your system.
