# CVE-2024-50176: remoteproc: k3-r5: Fix error handling when power-up failed

> A null pointer dereference in the Linux kernel's k3-r5 remoteproc driver can cause a system crash during shutdown if power-up fails.

- **Severity:** Medium 5.5 (`CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H`)
- **Exploited in the wild:** Not known
- **Login needed:** Any signed-in user
- **Attackable:** Local or same network only
- **Victim action needed:** Not needed
- **Fix available:** Yes
- **Published:** 8 Nov 2024
- **Updated:** 23 May 2026
- **Also known as:** BELL-CVE-2024-50176, DEBIAN-CVE-2024-50176, GHSA-x6rf-4v3v-mfmw, UBUNTU-CVE-2024-50176

## What is CVE-2024-50176?

CVE-2024-50176 is a medium-severity vulnerability in Linux kernel, published on 8 Nov 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:

remoteproc: k3-r5: Fix error handling when power-up failed

By simply bailing out, the driver was violating its rule and internal
assumptions that either both or no rproc should be initialized. E.g.,
this could cause the first core to be available but not the second one,
leading to crashes on its shutdown later on while trying to dereference
that second instance.

Weakness: CWE-755 (Improper Handling of Exceptional Conditions)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-50176 and fix it if it is affected.

What it is: CVE-2024-50176 is a medium-severity vulnerability in Linux kernel, published on 8 Nov 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-2024-50176 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.
