The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 host has packages installed that are affected by a vulnerability as referenced in the USN-8119-1 advisory.

    It was discovered that systemd incorrectly handled certain cgroup paths. A local attacker could possibly     use this issue to cause systemd to crash, resulting in a denial of service. (CVE-2026-29111)

    It was discovered that the systemd udev component incorrectly handled certain fields received from the     kernel. An attacker with a malicious device could possibly use this issue to execute arbitrary code as an     administrator (root).

    Package        : systemd     Version        : 247.3-7+deb11u8     CVE ID         : CVE-2026-4105 CVE-2026-29111 CVE-2026-40225 CVE-2026-40226     Debian Bug     :

    The following vulnerabilities have been discovered systemd:

    CVE-2026-4105

        The systemd-machined service contains an Improper Access Control         vulnerability due to insufficient validation of the class parameter in         the RegisterMachine D-Bus (Desktop Bus) method. A local unprivileged         user can exploit this by attempting to register a machine with a         specific class value, which may leave behind a usable,         attacker-controlled machine object. This allows the attacker to invoke         methods on the privileged object, leading to the execution of         arbitrary commands with root privileges on the host system.

    CVE-2026-29111

        When an unprivileged IPC API call is made with spurious data, a stack         overwrite occurs, with the attacker controlled content.

    CVE-2026-40225

        udev: local root execution can occur via malicious hardware devices         and unsanitized kernel output.

    CVE-2026-40226

        nspawn: an escape-to-host action can occur via a crafted optional         config file.

    For Debian 11 bullseye, these problems have been fixed in version     247.3-7+deb11u8.

    We recommend that you upgrade your systemd packages.

An update of the systemd package has been released.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - systemd, a system and service manager, (as PID 1) hits an assert and freezes execution when an     unprivileged IPC API call is made with spurious data. On version v249 and older the effect is not an     assert, but stack overwriting, with the attacker controlled content. From version v250 and newer this is     not possible as the safety check causes an assert instead. This IPC call was added in v239, so versions     older than that are not affected. Versions 260-rc1, 259.2, 258.5, and 257.11 contain patches. No known     workarounds are available. (CVE-2026-29111)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote AlmaLinux 9 host has packages installed that are affected by a vulnerability as referenced in the ALSA-2026:13677 advisory.

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2026:13651 advisory.

    The systemd packages contain systemd, a system and service manager for Linux, compatible with the SysV and     LSB init scripts. It provides aggressive parallelism capabilities, uses socket and D-Bus activation for     starting services, offers on-demand starting of daemons, and keeps track of processes using Linux cgroups.
    In addition, it supports snapshotting and restoring of the system state, maintains mount and automount     points, and implements an elaborate transactional dependency-based service control logic. It can also work     as a drop-in replacement for sysvinit.

    Security Fix(es):

    * systemd: systemd: Arbitrary code execution or Denial of Service via spurious IPC API call data     (CVE-2026-29111)
