Unity Linux 20.1050e Security Update: kernel (UTSA-2026-005077)

high Nessus Plugin ID 296832

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-2026-005077 advisory.

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

 ima: Fix use-after-free on a dentry's dname.name

 ->d_name.name can change on rename and the earlier value can be freed;
 there are conditions sufficient to stabilize it (->d_lock on dentry,
 ->d_lock on its parent, ->i_rwsem exclusive on the parent's inode, rename_lock), but none of those are met at any of the sites. Take a stable snapshot of the name instead.

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.
