Control-flow hijacking, which allows an attacker to execute arbitrary code, remains a dangerous software vulnerability. Control-flow hijacking in speculated or transient execution is particularly insidious as it allows attackers to leak data from operating system kernels and other targets on commodity hardware, even in the absence of software bugs. Having made the jump from regular to transient execution in recent attacks, control-flow hijacking has become a top priority for developers. While powerful defenses against control-flow hijacking in regular execution are now sufficiently low-overhead to see wide-spread adoption, this is not the case for defenses in transient execution. Unfortunately, current techniques for mitigating attacks in transient execution exhibit high overheads—requiring a costly combination of defenses for every indirect branch.
