Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-000907)

medium Nessus Plugin ID 283820

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-2026-000907 advisory.

The tipc_nl_compat_link_dump function in net/tipc/netlink_compat.c in the Linux kernel through 4.6.3 does not properly copy a certain string, which allows local users to obtain sensitive information from kernel stack memory by reading a Netlink message.

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.
