Unity Linux 20.1070e Security Update: kernel (UTSA-2025-989861)

medium Nessus Plugin ID 273413

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-2025-989861 advisory.

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

 NFSD: Prevent a potential integer overflow

 If the tag length is >= U32_MAX - 3 then the length + 4 addition can result in an integer overflow. Address this by splitting the decoding into several steps so that decode_cb_compound4res() does not have to perform arithmetic on the unsafe length value.

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.
