## What is CVE-2025-38619?

CVE-2025-38619 is a high-severity vulnerability in Linux kernel, published on 22 Aug 2025. 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:

media: ti: j721e-csi2rx: fix list_del corruption

If ti_csi2rx_start_dma() fails in ti_csi2rx_dma_callback(), the buffer is
marked done with VB2_BUF_STATE_ERROR but is not removed from the DMA queue.
This causes the same buffer to be retried in the next iteration, resulting
in a double list_del() and eventual list corruption.

Fix this by removing the buffer from the queue before calling
vb2_buffer_done() on error.

This resolves a crash due to list_del corruption:

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2025-38619 and fix it if it is affected.

What it is: CVE-2025-38619 is a high-severity vulnerability in Linux kernel, published on 22 Aug 2025. 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-2025-38619 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.
