"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-126 advisory.

  - 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. (CVE-2022-41973)

  - 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)

  - device-mapper-multipath: Regression of CVE-2022-41974 fix in Red Hat Enterprise Linux (CVE-2022-3787)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
