# CVE-2026-43235: media: iris: Add missing platform data entries for SM8750

> Missing platform data entries in the Linux kernel iris driver cause decode/encode failures, resulting in a denial of service for media sessions.

- **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:** 6 May 2026
- **Updated:** 11 May 2026
- **Also known as:** BELL-CVE-2026-43235, DEBIAN-CVE-2026-43235, GHSA-9g4v-54hx-cw68, UBUNTU-CVE-2026-43235

## What is CVE-2026-43235?

CVE-2026-43235 is a medium-severity denial of service vulnerability in Linux kernel, published on 6 May 2026. 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: iris: Add missing platform data entries for SM8750

Two platform-data fields for SM8750 were missed:

  - get_vpu_buffer_size = iris_vpu33_buf_size
    Without this, the driver fails to allocate the required internal
    buffers, leading to basic decode/encode failures during session
    bring-up.

  - max_core_mbps = ((7680 * 4320) / 256) * 60
    Without this capability exposed, capability checks are incomplete and
    v4l2-compliance for encoder fails.

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2026-43235 and fix it if it is affected.

What it is: CVE-2026-43235 is a medium-severity denial of service vulnerability in Linux kernel, published on 6 May 2026. 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-2026-43235 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.
