Unity Linux 20.1050a Security Update: kernel (UTSA-2026-098986)

high Nessus Plugin ID 340571

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-098986 advisory.

In the Linux kernel, the following vulnerability has been resolved:

libceph: make decode_pool() more resilient against corrupted osdmaps

If the osdmap is (maliciously) corrupted such that the encoded length of ceph_pg_pool envelope is less than what is expected for a particular encoding version, out-of-bounds reads may ensue because the only bounds check that is there is based on that length value.

This patch adds explicit bounds checks for each field that is decoded or skipped.

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

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

Solution

Update the affected kernel package.
