If you're working on a Kotlin Compiler Plugin, I've been putting the Gradle boilerplate code to setup the test framework under the rug^H^H in a separate plugin 😄

Really great read by @h0mbre (on X) about his journey to exploit a Linux n-day on kCTF. Not only the exploit but the process to understand the bug including own failures, e.g. deal with CONFIG_DEBUG_LIST, is full of insights. h0mbre.github.io/Patch_Gappin...
