## What is CVE-2026-80114?

CVE-2026-80114 is a high-severity vulnerability in PassMark Software BurnInTest, published on 4 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

PassMark PerformanceTest before 11.1 build 1012, BurnInTest before 11.1 build 1000, and OSForensics before 11.1 build 1016 contain a hard-coded credentials vulnerability in DirectIo64.sys that allows local attackers to perform arbitrary physical memory writes by extracting an 8-byte key embedded as a hardcoded literal in the distributed binary and computing valid MD5 authentication tags for arbitrary IOCTL write requests. Attackers can additionally bypass a secondary validation gate by using the driver's own bit-clear IOCTL to clear a single bit in the gating instruction's displacement byte, causing all subsequent write requests to skip MAC verification, size checks, and Vendor ID checks entirely.

Weakness: CWE-321 (Use of Hard-coded Cryptographic Key)

Check this codebase for CVE-2026-80114 and fix it if it is affected.

What it is: CVE-2026-80114 is a high-severity vulnerability in PassMark Software BurnInTest, published on 4 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-80114 exists.

Affected product: PassMark Software BurnInTest. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
