# CVE-2024-41038: firmware: cs_dsp: Prevent buffer overrun when processing V2 alg headers

> A buffer overrun in the Linux kernel's cs_dsp firmware driver allows attackers to cause memory corruption, potentially leading to code execution or system crashes.

- **Severity:** High 7.8 (`CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H`)
- **Exploited in the wild:** Not known
- **Login needed:** Not needed
- **Attackable:** Local or same network only
- **Victim action needed:** A user has to click or open something
- **Fix available:** Yes
- **Published:** 29 Jul 2024
- **Updated:** 5 Aug 2026
- **Also known as:** AZL-47489, BELL-CVE-2024-41038, DEBIAN-CVE-2024-41038, GHSA-8qxj-f84c-r77w, UBUNTU-CVE-2024-41038

## What is CVE-2024-41038?

CVE-2024-41038 is a high-severity memory corruption vulnerability in Linux kernel, published on 29 Jul 2024. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.

### Official description

In the Linux kernel, the following vulnerability has been resolved:

firmware: cs_dsp: Prevent buffer overrun when processing V2 alg headers

Check that all fields of a V2 algorithm header fit into the available
firmware data buffer.

The wmfw V2 format introduced variable-length strings in the algorithm
block header. This means the overall header length is variable, and the
position of most fields varies depending on the length of the string
fields. Each field must be checked to ensure that it does not overflow
the firmware data buffer.

As this ia bugfix patch, the fixes avoid making any significant change to
the existing code. This makes it easier to review and less likely to
introduce new bugs.

Weakness: CWE-120 (Buffer Copy without Checking Size of Input)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-41038 and fix it if it is affected.

What it is: CVE-2024-41038 is a high-severity memory corruption vulnerability in Linux kernel, published on 29 Jul 2024. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Exploitation: There is no known exploitation of CVE-2024-41038 in the wild and no public exploit code.

Affected product: Linux kernel. 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.
