 ## Reporting a Vulnerability
 
 We receive security vulnerability reports through GitHub Security Advisories.
+If AI assistance contributed to your finding, do not file a private advisory:
+read [AI-Assisted Discovery](#ai-assisted-discovery) instead.
 
 To begin a report, go to the [PX4/PX4-Autopilot](https://github.com/PX4/PX4-Autopilot) repository
 and click on the **Security** tab. If you are on mobile, click the **...** dropdown menu, then click **Security**.

+## AI-Assisted Discovery
+
+We align with the [Linux kernel security policy](https://docs.kernel.org/process/security-bugs.html)
+on AI-assisted bug discovery.
+
+If you used AI assistance to identify a bug, treat it as public. You may have
+good reasons to believe it is not, but both the kernel security team and PX4
+maintainers have seen bugs found this way surface across multiple researchers
+at the same time, often on the same day. Instead of filing a private advisory,
+open a pull request with a fix. If you cannot submit a fix yourself, first
+search the [open pull requests](https://github.com/PX4/PX4-Autopilot/pulls)
+for one that already addresses it; only if nothing exists, open an
+[issue](https://github.com/PX4/PX4-Autopilot/issues/new/choose).
+
+Your pull request makes the bug public, and that is expected. The reproducer
+is different: never post it publicly, it works against vehicles in the field
+until the fix ships. Describe the demonstrated impact in the pull request,
+state that a reproducer is available, and maintainers will ask for it
+privately if they need it.
+
+### Responsible Use of AI to Find Bugs
+
+A growing share of incoming security reports comes from AI-assisted code review.
+It can surface real bugs in rarely exercised code, but it also floods
+maintainers with low-quality reports. If AI tooling contributed to your finding,
+the guidance above applies, and so do the following points:
+
+- **Length**: Lead with a short summary: the affected module or file, the
+  affected versions, and the demonstrated impact. AI tools tend to produce pages
+  of sections and filler. Configure yours to write a concise, human-style
+  report. Triage should never require scanning pages of text to find the
+  essential facts.
+- **Signal over noise**: Skip boilerplate sections and decorative structure that
+  bury the facts. State only what you have demonstrated, in concrete PX4 terms:
+  what an attacker on the MAVLink link, RC link, or CAN bus can actually do,
+  such as write a parameter, change flight mode, arm the vehicle, or upload
+  firmware. Do not enumerate speculative consequences.
+- **Reproducer**: Have your tool produce a reproducer and test it yourself. A
+  reproducer that works against SITL (`make px4_sitl`) is the gold standard. If
+  it does not work, or the tool cannot produce one, treat the report itself as
+  suspect. As stated above, do not post the reproducer publicly. Mention that
+  it exists and share it with maintainers on request.
+- **Propose a fix**: AI tools are often better at writing code than judging it.
+  Have your tool propose a fix and test it before you report: in SITL at
+  minimum, on hardware if the code path requires it. If the fix cannot be tested
+  because it depends on hardware nobody has, the issue is likely not a real
+  security bug. Fixes must follow the [contribution guide](CONTRIBUTING.md).
+
+Reports that disregard these points risk being ignored.
+
+Use common sense before filing. If the affected code is a driver for a
+discontinued board or a rarely used peripheral and has not been touched in
+years, exposed users are probably close to zero and the report is not worth a
+maintainer's time. If the issue is trivial and publicly discoverable, take it
+straight through the flow above: a public pull request, or an issue as a last
+resort.
