## What is CVE-2026-41155?

CVE-2026-41155 is a medium-severity vulnerability in Imagination Technologies Graphics DDK, published on 12 Jun 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

An attacker could cooperatively pass data from one secure GPU process to another secure GPU process through shared secure memory allocations in the kernel module. Additionally, an attacker could disrupt the operation of another secure GPU process leading to image corruption / GPU hardware recovery.

Sharing secure memory allocations among various GPU secure processes allows an attacker to corrupt shared resource affecting other users.

Weakness: CWE-653 (Improper Isolation or Compartmentalization)

Check this codebase for CVE-2026-41155 and fix it if it is affected.

What it is: CVE-2026-41155 is a medium-severity vulnerability in Imagination Technologies Graphics DDK, published on 12 Jun 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-41155 in the wild and no public exploit code.

Affected product: Imagination Technologies Graphics DDK. 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.
