Unity Linux 20.1050e Security Update: kernel (UTSA-2026-006577)

high Nessus Plugin ID 305319

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-2026-006577 advisory.

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

gfs2: Fix possible data races in gfs2_show_options()

Some fields such as gt_logd_secs of the struct gfs2_tune are accessed without holding the lock gt_spin in gfs2_show_options():

val = sdp->sd_tune.gt_logd_secs;
if (val != 30) seq_printf(s, ,commit=%d, val);

And thus can cause data races when gfs2_show_options() and other functions such as gfs2_reconfigure() are concurrently executed:

spin_lock(>->gt_spin);
gt->gt_logd_secs = newargs->ar_commit;

To fix these possible data races, the lock sdp->sd_tune.gt_spin is acquired before accessing the fields of gfs2_tune and released after these accesses.

Further changes by Andreas:

- Don't hold the spin lock over the seq_printf operations.

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.
