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-2026-011066 advisory.

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

um: vector: Fix memory leak in vector_config

If the return value of the uml_parse_vector_ifspec function is NULL, we should call kfree(params) to prevent memory leak.
