Unity Linux 20.1070e Security Update: kernel (UTSA-2026-131750)

critical Nessus Plugin ID 366617

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-2026-131750 advisory.

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

fs/ntfs3: call _ntfs_bad_inode() when failing to rename

It is safe to call _ntfs_bad_inode on live inodes since:
commit 519b078998ce (fs/ntfs3: Exclude call make_bad_inode for live nodes.)

The WARN_ON was added when it wasn't safe by:
commit d99208b91933 (fs/ntfs3: cancle set bad inode after removing name fails)

Replace the WARN_ON with a call to _ntfs_bad_inode() to prevent further operations on the inconsistent inode.

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.
