How easy is CVE-2026-23918 to trigger?
🔸 One TCP connection.
🔸 Two frames.
🔸 HEADERS + immediate RST_STREAM (non-zero error code).
That’s it → double-free in mod_http2, worker crashes.
Researchers built a working RCE PoC using Apache’s fixed scoreboard + mmap allocator (default on Debian & official Docker).
If you’re on 2.4.66 with mod_http2 + threaded MPM: patch to 2.4.67 now. (prefork MPM is safe)
