Overview

CVE-2023-53622 is a high-severity vulnerability. It was published on October 7, 2025 and has a CVSS 3.1 base score of 7.0 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.0, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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->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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.

How can CyberStrike help with CVE-2023-53622?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2023-53622 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
