Synopsis

The remote Ubuntu host is missing a security update.

Description

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).
