Unity Linux 20.1070a Security Update: kernel (UTSA-2025-986370)

medium Nessus Plugin ID 268087

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-2025-986370 advisory.

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

 NFSv4: Don't hold the layoutget locks across multiple RPC calls

 When doing layoutget as part of the open() compound, we have to be careful to release the layout locks before we can call any further RPC calls, such as setattr(). The reason is that those calls could trigger a recall, which could deadlock.

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.
