Unity Linux 20.1050e Security Update: kernel (UTSA-2026-006772)

medium Nessus Plugin ID 305377

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-2026-006772 advisory.

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

ipv6: fix potential struct net leak in inet6_rtm_getaddr()

It seems that if userspace provides a correct IFA_TARGET_NETNSID value but no IFA_ADDRESS and IFA_LOCAL attributes, inet6_rtm_getaddr() returns -EINVAL with an elevated struct net refcount.

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.
