## What is CVE-2017-9150?

CVE-2017-9150 is a medium-severity vulnerability in Linux kernel, published on 22 May 2017. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

The do_check function in kernel/bpf/verifier.c in the Linux kernel before 4.11.1 does not make the allow_ptr_leaks value available for restricting the output of the print_bpf_insn function, which allows local users to obtain sensitive address information via crafted bpf system calls.

Weakness: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2017-9150 and fix it if it is affected.

What it is: CVE-2017-9150 is a medium-severity vulnerability in Linux kernel, published on 22 May 2017. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2017-9150 exists.

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.
