TencentOS Server 4: systemd (TSSA-2026:0870)

medium Nessus Plugin ID 342064

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2026:0870 advisory.

Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

CVE-2026-16742:
systemd-homed contains a local privilege escalation bug via arbitrary system group addition to a local, logged in, homed-managed user

CVE-2026-15059:
Local unprivileged users can terminate arbitrary local processes via a systemd-oomd IPC API due to a missing path traversal validation.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

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

Solution

Update the affected packages.
