RHEL 8 : device-mapper-multipath (RHSA-2022:7188)

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2022:7188 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.
