    Package        : udisks2
    Version        : 2.9.2-2+deb11u3
    CVE ID         : CVE-2025-8067


    Michael Imfeld discovered an out-of-bounds read vulnerability in udisks2,
    which may result in denial of service (daemon process crash), or in
    mapping an internal file descriptor from the daemon process onto a loop
    device, resulting in local privilege escalation.



    For Debian 11 bullseye, this problem has been fixed in version
    2.9.2-2+deb11u3.

    We recommend that you upgrade your udisks2 packages.

    For the detailed security status of udisks2 please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/udisks2

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