Summary
Kingston FURY CTRL RGB Control Software has a flaw in its NTIOLib_X64.sys library, where an IOCTL interface is exposed with insufficient access control. An attacker who already has local access and high-level privileges on the machine could use it to gain full control over the system.
Written by anthropic/claude-haiku-5.5 from the sources below. Verify against them.

Check your systems with an agent
Paste this into a coding or ops agent. It checks your systems read-only and reports a table per asset.
Check whether my systems are affected by CVE-2026-129261 (Kingston FURY CTRL RGB Control Software IOCTL NTIOLib_X64.sys exposed ioctl with insufficient access control), 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-2026-129261 (entry last updated 2026-11-14):
Affected:
- Kingston FURY CTRL RGB Control Software: versions 2.0.0, 2.0.1, 2.0.2, 2.0.3, 2.0.4, 2.0.5, 2.0.6, 2.0.7, 2.0.8, 2.0.9, 2.0.10, 2.0.11 and 55 more
Fixed versions: none listed yet.
Setup: unknown whether the bug needs a non-default feature or setting. Check the advisory.
CISA KEV: CVE-2026-129261 is not listed as of cve.now's last read.
This KEV status is for CVE-2026-129261 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://vuldb.com/vuln/437302
- https://vuldb.com/vuln/437302/cti
- https://vuldb.com/cve/CVE-2026-129261
- https://vuldb.com/submit/1043190
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.
