Unity Linux 20.1070e Security Update: kernel (UTSA-2025-987108)

medium Nessus Plugin ID 269086

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-2025-987108 advisory.

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

 NFSv4.2: fix reference count leaks in _nfs42_proc_copy_notify()

 [You don't often get email from [email protected]. Learn why this is important at http://aka.ms/LearnAboutSenderIdentification.]

 The reference counting issue happens in two error paths in the function _nfs42_proc_copy_notify(). In both error paths, the function simply returns the error code and forgets to balance the refcount of object `ctx`, bumped by get_nfs_open_context() earlier, which may cause refcount leaks.

 Fix it by balancing refcount of the `ctx` object before the function returns in both error paths.

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.
