On the Effectiveness of Hardware Mitigations Against Cross-Privilege Spectre-v2 Attacks BHI (or Spectre-BHB) is a revival of cross-privilege Spectre-v2 attacks on modern systems deploying in-hardware defenses. And we have a very neat end-to-end exploit leaking arbitrary kernel memory on modern Intel CPUs to prove it (PoC||GTFO right?).

After further investigation, we found that SysJoker also has Mach-O and Windows PE versions." -Intezer*
