## What is CVE-2024-49200?

CVE-2024-49200 is a medium-severity memory corruption vulnerability in n/a, published on 15 Apr 2025. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

An issue was discovered in AcpiS3SaveDxe and ChipsetSvcDxe in Insyde InsydeH2O with kernel 5.2 though 5.7. A potential DXE memory corruption vulnerability has been identified. The root cause is use of a pointer originating from the value of an NVRAM variable as the target of a write operation. This can be leveraged by an attacker to perform arbitrary writes, potentially leading to arbitrary code execution. The issue has been fixed in kernel 5.2, Version 05.29.44; kernel 5.3, Version 05.38.44; kernel 5.4, Version 05.46.44; kernel 5.5, Version 05.54.44; kernel 5.6, Version 05.61.44; and kernel 5.7, Version 05.70.44.

Weakness: CWE-787 (Out-of-bounds Write)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-49200 and fix it if it is affected.

What it is: CVE-2024-49200 is a medium-severity memory corruption vulnerability in n/a, published on 15 Apr 2025. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2024-49200 in the wild and no public exploit code.

Affected product: n/a. 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.
