## What is CVE-2024-35913?

CVE-2024-35913 is a high-severity vulnerability in Linux kernel, published on 19 May 2024. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

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

wifi: iwlwifi: mvm: pick the version of SESSION_PROTECTION_NOTIF

When we want to know whether we should look for the mac_id or the
link_id in struct iwl_mvm_session_prot_notif, we should look at the
version of SESSION_PROTECTION_NOTIF.

This causes WARNINGs:

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-35913 and fix it if it is affected.

What it is: CVE-2024-35913 is a high-severity vulnerability in Linux kernel, published on 19 May 2024. 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-2024-35913 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.
