Hi,
Our team recently developed a null-pointer-dereference (NPD) vulnerability detection tool
OK, so you decided to write a new tool. Good for you, but keep in mind that you need to compete with very well-known tools already.
After manual review,
(and you have:)
BUILD_BUG_ON(ARRAY_SIZE(direction) != ARRAY_SIZE(elems->ttlm));
So you're either lying, or decided to task someone with this who doesn't understand C; even state-of-the art LLMs would do better. State of the art tools (LLMs and not LLMs like coverity) will also give you a scenario of how the purported bug can actually happen. I get that you need human feedback to improve your system, but you've also apparently decided that it's too expensive / too much work / too hard to really do this review, and you want the Linux community to do it for you instead. That's cheaper, yay! But it doesn't work that way. You're not entitled to free feedback for your under development tool. Please stop doing this. johannes
