### Official description

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

media: atomisp: Add check for rgby_data memory allocation failure

In ia_css_3a_statistics_allocate(), there is no check on the allocation
result of the rgby_data memory. If rgby_data is not successfully
allocated, it may trigger the assert(host_stats->rgby_data) assertion in
ia_css_s3a_hmem_decode(). Adding a check to fix this potential issue.

Weakness: CWE-617 (Reachable Assertion)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-56705 and fix it if it is affected.

What it is: CVE-2024-56705 is a medium-severity vulnerability in Debian Debian Linux, published on 28 Dec 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-2024-56705 in the wild and no public exploit code.

Affected product: Debian Debian Linux. 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.
