| * | [X86] Fix to X86LoadValueInjectionRetHardeningPass for possible segfault | Scott Constable | 2020-06-24 | 1 | -0/+3 |
| | | | | | | | `MBB.back()` could segfault if `MBB.empty()`. Fixed by checking for `MBB.empty()` in the loop. Differential Revision: https://reviews.llvm.org/D77584 | ||||
| * | [X86] Add RET-hardening Support to mitigate Load Value Injection (LVI) | Scott Constable | 2020-06-24 | 1 | -0/+140 |
| Adding a pass that replaces every ret instruction with the sequence: pop <scratch-reg> lfence jmp *<scratch-reg> where <scratch-reg> is some available scratch register, according to the calling convention of the function being mitigated.
