## What is CVE-2024-28115?

CVE-2024-28115 is a high-severity vulnerability in FreeRTOS-Kernel, published on 7 Mar 2024. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

FreeRTOS is a real-time operating system for microcontrollers. FreeRTOS Kernel versions through 10.6.1 do not sufficiently protect against local privilege escalation via Return Oriented Programming techniques should a vulnerability exist that allows code injection and execution. These issues affect ARMv7-M MPU ports, and ARMv8-M ports with Memory Protected Unit (MPU) support enabled (i.e. `configENABLE_MPU` set to 1). These issues are fixed in version 10.6.2 with a new MPU wrapper.

Weakness: CWE-284 (Improper Access Control)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-28115 and fix it if it is affected.

What it is: CVE-2024-28115 is a high-severity vulnerability in FreeRTOS-Kernel, published on 7 Mar 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-2024-28115 in the wild and no public exploit code.

Affected product: FreeRTOS-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.
