## What is CVE-2024-6246?

CVE-2024-6246 is a critical memory corruption vulnerability in Wyze Cam v3, published on 22 Nov 2024. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Wyze Cam v3 Realtek Wi-Fi Driver Heap-Based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Wyze Cam v3 IP cameras. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the Realtek Wi-Fi kernel module. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the kernel. Was ZDI-CAN-22310.

Weakness: CWE-787 (Out-of-bounds Write), CWE-122 (Heap-based Buffer Overflow)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2024-6246 and fix it if it is affected.

What it is: CVE-2024-6246 is a critical memory corruption vulnerability in Wyze Cam v3, published on 22 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-2024-6246 in the wild and no public exploit code.

Affected product: Wyze Cam v3. 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.
