CVE-2026-108472 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 7.8 (high) and affects Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8 and 3 more; no fixed version is listed; see the vendor advisory.

## Summary

The xfsprogs package, used by Red Hat Enterprise Linux and several Red Hat OpenShift Container Platform images, has a flaw in its xfs_admin utility that fails to properly validate user-supplied parameters. A local attacker with low-privileged access can supply crafted arguments to run arbitrary operating system commands, which may lead to privilege escalation depending on how xfs_admin is run.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Who should check

Teams with scripts, delegation or provisioning tools that pass parameters to xfs_admin in xfsprogs on Red Hat Enterprise Linux 7-10 or OpenShift Container Platform 4/5

## Affected

- xfsprogs: version range not reported
- xfsprogs: version range not reported
- xfsprogs: version range not reported
- xfsprogs: version range not reported
- openshift/ose-rhel-coreos-8: version range not reported

## Description

A flaw was found in the xfs_admin utility in xfsprogs. The tool does not properly validate user-supplied parameters, allowing operating system command injection. A local attacker can exploit this issue by providing crafted input arguments, which may result in arbitrary command execution and local privilege escalation depending on how xfs_admin is executed.

## What to do

- Check your stack: if you ship or depend on xfsprogs, openshift/ose-rhel-coreos-8, openshift/ose-rhel-coreos-9, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, run the stack.check operation (execute) on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile.

## Check your systems with an agent

```text
Check whether my systems are affected by CVE-2026-108472 (Xfsprogs: xfsprogs: local privilege escalation via command injection in xfs_admin), using the cve.now data below.

Rules: work read-only. Do not run exploit code, proof-of-concept scripts or scanners that send attack payloads, and do not change any configuration, package, image or deployment. Report findings only.

What cve.now has for CVE-2026-108472 (entry last updated 2026-11-11):
Affected:
- Red Hat Red Hat Enterprise Linux 10: version range not reported
- Red Hat Red Hat Enterprise Linux 7: version range not reported
- Red Hat Red Hat Enterprise Linux 8: version range not reported
- Red Hat Red Hat Enterprise Linux 9: version range not reported
- Red Hat Red Hat OpenShift Container Platform 4: version range not reported
- Red Hat Red Hat OpenShift Container Platform 4: version range not reported
- Red Hat Red Hat OpenShift Container Platform 5: version range not reported
Fixed versions: none listed yet.
Conditions (all must be true for the bug to be hit):
- Untrusted inputs are passed to xfs_admin without proper validation (source: https://access.redhat.com/security/cve/cve-2026-108472)
Setup: the bug needs a feature or setting that is off by default or uncommon. Check whether each asset has it on.
Attacker needs: local access, low-privilege login, no user action.
CISA KEV: CVE-2026-108472 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-108472 only. If you also check another CVE, look up its own KEV status; never assume it from this one.

How to check:
- Installed software: check what is actually running, not what a repo declares. Read the version from each host, container image and Kubernetes node (the binary's version output, the OS package database, image layers), and check whether the conditions above hold there. Distribution packages may carry a backported fix under an older version number; confirm against the distribution's own advisory.

Verify against the linked advisories before concluding, and cite the date you read each one:

- https://access.redhat.com/security/cve/cve-2026-108472
Do not conclude an asset is unaffected unless you checked it and the evidence covers both its version and the conditions above. If you could not check something, mark it unknown and say what is missing.

Report a table with one row per asset and these columns: Asset | Version or build | Status (affected, fixed, not applicable, unknown) | Compensating controls | Exposure (internet-facing, internal, none) | Evidence | Next action.

## FAQ

### Is CVE-2026-108472 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

Source: https://cve.now/CVE-2026-108472

### What does this mean?

The xfs_admin tool can be made to run arbitrary operating system commands when it receives untrusted input without proper validation. The command runs with the permissions of the executing process, which may allow local privilege escalation.

Source: https://access.redhat.com/security/cve/cve-2026-108472

### Am I affected, and how do I check?

The listed products are Red Hat Enterprise Linux 7, 8, 9 and 10 and Red Hat OpenShift Container Platform 4 and 5. The stated condition is an environment where untrusted inputs are passed to xfs_admin without proper validation. The facts do not give affected version numbers, so check the product and version on your system against the vendor advisory.

Source: https://access.redhat.com/security/cve/cve-2026-108472

### How do I fix CVE-2026-108472?

The facts do not list a fixed version or an upgrade target. Follow the vendor advisory for updates to the affected products as they become available.

Source: https://access.redhat.com/security/cve/cve-2026-108472

### What if there's no patch?

The facts do not give a workaround. The only stated risk condition is passing untrusted inputs to xfs_admin without validation, so avoiding that pattern is the limit the facts support.
