Unity Linux 20.1070e Security Update: kernel (UTSA-2025-987244)

high Nessus Plugin ID 268906

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-2025-987244 advisory.

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

wifi: cfg80211: fix buffer overflow in elem comparison

For vendor elements, the code here assumes that 5 octets are present without checking. Since the element itself is already checked to fit, we only need to check the length.

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.
