Researchers publish OpenBSD root exploit chaining 37-year-old bug
Why it matters for readers: It shows how security researchers chain multiple bugs to bypass modern defenses and achieve root access.
- Calif published a local privilege escalation exploit that achieves root on OpenBSD 7.9.1
- The exploit chains an approximately 37-year-old integer overflow in shared memory with a separate kernel flaw.1
- The chain bypasses OpenBSD's KARL kernel-address randomization and hardware protections SMAP and SMEP.1
- Calif released a detailed writeup and full proof-of-concept code after OpenBSD shipped.1
