Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-011133)

medium Nessus Plugin ID 309041

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-2026-011133 advisory.

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

ext4: fix inode leak in ext4_xattr_inode_create() on an error path

There is issue as follows when do setxattr with inject fault:

[localhost]# fsck.ext4 -fn /dev/sda e2fsck 1.46.6-rc1 (12-Sep-2022) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Unattached zero-length inode 15. Clear? no

Unattached inode 15 Connect to /lost+found? no

Pass 5: Checking group summary information

/dev/sda: ********** WARNING: Filesystem still has errors **********

/dev/sda: 15/655360 files (0.0% non-contiguous), 66755/2621440 blocks

This occurs in 'ext4_xattr_inode_create()'. If 'ext4_mark_inode_dirty()' fails, dropping i_nlink of the inode is needed. Or will lead to inode leak.

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.
