Phoronix: LLVM Lands Performance-Hitting Mitigation For Intel LVI Vulnerability
Made public in March was the Load Value Injection (LVI) attack affecting Intel CPUs with SGX capabilities. LVI combines Spectre-style code gadgets with Meltdown-type illegal data flows to bypass existing defenses and allow injecting data into a victim's transient execution. While mitigations on the GNU side quickly landed, the LLVM compiler mitigations were just merged today.
