Alexis Lothoré has been working to add support for the kernel's memory-access checker,
KASAN, to just-in-time-compiled BPF code. He spoke about that work at the 2026
Linux Storage, Filesystem, Memory-Management, and BPF Summit. KASAN support is needed, he said, to help catch bugs in the BPF just-in-time (JIT) compiler. KASAN is a great tool for catching memory-management problems in the kernel, but only in code that can be monitored by it.
