CVE-2020-10060 is a high-severity vulnerability in Zephyrproject Zephyr, published on 11 May 2020. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

In updatehub_probe, right after JSON parsing is complete, objects\[1] is accessed from the output structure in two different places. If the JSON contained less than two elements, this access would reference unitialized stack memory. This could result in a crash, denial of service, or possibly an information leak. Provided the fix in CVE-2020-10059 is applied, the attack requires compromise of the server. See NCC-ZEP-030 This issue affects: zephyrproject-rtos zephyr version 2.1.0 and later versions. version 2.2.0 and later versions.

Weakness: CWE-824 (Access of Uninitialized Pointer), CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2020-10060 and fix it if it is affected.

What it is: CVE-2020-10060 is a high-severity vulnerability in Zephyrproject Zephyr, published on 11 May 2020. An attacker needs administrator access to exploit it, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2020-10060 in the wild and no public exploit code.

Affected product: Zephyrproject Zephyr. 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.
