how to report AI-detected Linux kernel bugs to cut duplicate noise and get fixes merged faster now
Learn how to report AI-detected Linux kernel bugs the right way: confirm on current mainline, search for duplicates, post on public lists, explain real impact, and include a tested patch. Choose the right maintainers, share a reproducer and tool output, and follow up in-thread. Skip private “security” mail for non-embargoed AI findings.
AI tools now flag many kernel issues, but many reports are duplicates, irrelevant, or already fixed. Linus Torvalds says AI is great when it helps, not when it creates churn. This guide shows how to report AI-detected Linux kernel bugs so maintainers can act fast and users benefit.
Why your AI-found bug needs extra care
AI scanners and LLMs often find the same pattern across the tree. Multiple people then send near-identical “security” mail, which hides discussion and wastes time. Kernel docs now stress: AI-found bugs are usually not secret. Use public lists so others can see, test, and help.
How to report AI-detected Linux kernel bugs the right way
Step 1: Reproduce on current kernels
Build and boot the latest mainline or release candidate if possible.
Test the latest stable for your distro or LTS branch.
Confirm the issue still exists; note exact versions and configs.
If it is static-only, try to produce a minimal code path or build warning.
Step 2: Check if it is already fixed or reported
Search lore.kernel.org for the file, function, or error text.
Scan recent commits for “Fixes:” lines that touch the code.
Look at subsystem mailing list archives and syzbot reports.
If a thread exists, reply there with new data instead of starting a new one.
Step 3: Decide the right channel: public vs private
Public is the default. Send to the subsystem list and maintainers from the MAINTAINERS file.
Use private security@kernel.org only when the issue is a clear, unpatched, high-impact security flaw that benefits from an embargo.
AI pattern matches and low-impact bugs are not confidential; report them publicly.
Step 4: Add value with a patch
Propose a fix, even if small. Compile-test it. Run basic runtime tests if you can.
Follow kernel style (checkpatch.pl) and include a good commit message (“why” first, then “how”).
Add “Fixes:” with the guilty commit, and “Reported-by:” to credit tools or helpers.
Send via git send-email to the right lists and maintainers.
Step 5: Write a clear, useful report
Include at least:
Subject: subsystem: short, specific problem summary (e.g., “net: foo: null deref on X path”).
Environment: kernel versions, distro, config options, hardware details.
Reproducer: steps, script, or minimal program; or exact static analysis path.
What you expected vs what happened: crash, info leak, use-after-free, deadlock, etc.
Impact and trigger: can an unprivileged user hit it? remote input? high-frequency path?
Logs: oops traces, WARNs, KASAN/KMSAN/KCSAN output, and relevant dmesg lines.
Tool output: name, version, rule, and why the finding is meaningful.
Step 6: Send it to the right people
Run scripts/get_maintainer.pl on your patch to find recipients.
CC the subsystem list(s) and relevant maintainers, not just LKML.
Group related patches into a series; keep each change focused and compile-tested.
Step 7: Follow up
Respond to review quickly. Explain your reasoning and answer questions.
Test suggested changes and report results.
If it was a duplicate, add extra testing or a better fix to move it forward.
What good impact analysis looks like
Security or not?
Security: bug crosses a privilege boundary, allows code execution, info leak, or reliable DoS by an untrusted user.
Non-security: build-only nit, unreachable path, obsolete or disabled driver with no users.
If unsure, state your best guess and why. Be honest about limits.
Old or orphaned drivers
If code is unmaintained and risky, consider proposing removal, deprecation, or marking BROKEN.
Explain real-world impact: who uses it, on what hardware, and how likely the bug is to trigger.
A simple email template you can adapt
Subject: subsystem: area: concise bug summary
Summary: one or two lines with the core problem and impact.
Versions: mainline/stable commit IDs or tags; config highlights.
Reproducer: exact steps or link to a gist; note if static-only.
Analysis: why it fails; pointer to lines/functions; tool output and version.
Impact: who can trigger; local/remote; privilege needed; data loss or crash details.
Patch: inline or linked; compile/test results; “Fixes:” and “Reported-by:” tags.
Common pitfalls to avoid
Do not paste an LLM-written patch you have not built or tested.
Do not send AI-found nits to the private security list.
Do not omit kernel versions, logs, or steps to reproduce.
Do not spam multiple lists with the same unmodified report.
Do not disappear after sending; reviews need your input.
Lightweight checklist before you hit send
Reproduced on current mainline or latest stable.
Searched lore.kernel.org and recent commits for duplicates/fixes.
Clear impact statement; security or not, and why.
Minimal reproducer or precise static path provided.
Patch included, checkpatch clean, compile-tested.
Right maintainers and lists in To/CC using get_maintainer.pl.
Public report unless a genuine embargo is needed.
Strong reports save maintainers time and get fixes merged faster. If you follow these steps on how to report AI-detected Linux kernel bugs, you will turn noisy findings into real progress. Add proof, context, and a patch, and your AI tool becomes a force multiplier—not a source of extra work.

FAQ
Q: What first steps should I take to confirm an AI-reported kernel bug?
A: Build and boot the latest mainline or a recent release candidate and test the latest stable or LTS branch if possible. Note exact kernel versions and config options and try to produce a minimal reproducer or a clear static-analysis path for static-only findings.
Q: How do I check if an AI-reported finding is already known or fixed?
A: Search lore.kernel.org for the file, function, or error text and scan recent commits for “Fixes:” lines that touch the code. Also check subsystem mailing list archives and syzbot reports, and reply to an existing thread with new data instead of starting a duplicate.
Q: When should I use public mailing lists versus private security channels?
A: Public is the default: send to the subsystem list and maintainers from the MAINTAINERS file so others can see and help. Use private security@kernel.org only for clear, unpatched, high-impact vulnerabilities that truly benefit from an embargo.
Q: How important is it to include a patch with an AI-detected bug report?
A: Proposing a fix, even a small one, adds real value; compile-test it, run basic runtime tests if you can, and follow kernel style with checkpatch.pl. Include a clear commit message explaining why and how, add “Fixes:” and “Reported-by:” tags where relevant, and send the patch via git send-email to the right lists.
Q: What details must I include to make a report useful to maintainers?
A: Provide a concise subject, environment details (kernel versions, distro, config), a minimal reproducer or exact static analysis path, expected versus actual behavior, and a clear impact and trigger description. Attach relevant logs such as oops traces or KASAN output and include the tool name, version, rule, and why the finding matters.
Q: How do I find and CC the correct maintainers and lists?
A: Run scripts/get_maintainer.pl on your patch to find recipients and CC the subsystem list(s) and relevant maintainers rather than only LKML. Group related changes into a focused series and ensure each patch is compile-tested before sending.
Q: How can I decide whether an AI-found issue is a security bug?
A: Assess whether the bug crosses a privilege boundary, allows code execution, causes a reliable information leak, or enables a DoS by an untrusted user—those are security-relevant. If it is a build-only nit, unreachable path, or an obsolete/unmaintained driver with no users, treat it as non-security and state your reasoning and limits.
Q: What common mistakes should I avoid when reporting AI-detected issues?
A: Avoid sending unbuilt LLM-written patches, filing the same unmodified report to multiple lists, sending AI-found nits to the private security list, omitting versions/logs/reproducers, or disappearing after sending. Follow a lightweight checklist—reproduce on current mainline, search lore.kernel.org, include impact and a tested patch, and follow up in-thread—as guidance on how to report AI-detected Linux kernel bugs.
