We encourage future research to investigate the applicability of LVI to non-Intel CPUs.How To Install linux-cloud-tools-common on Ubuntu 20.04 If an attacker finds software that uses these features in an exploitable way, LVI might still be possible. We maintain an up-to-date overview on the website (select Meltdown + vendor ARM or AMD). Some non-Intel processors have been shown to be affected by some variants of Meltdown and Foreshadow. ![]() However, following the argument of symmetry, in in principle any processor that is vulnerable to Meltdown-type data leakage, would also be vulnerable to LVI-style data injection. In our current assessment, LVI principally applies only to Intel processors with SGX technology. What about other processor vendors (ARM AMD, etc.)? LVI furthermore marks the end of transparently patching Meltdown-type processor vulnerabilities in CPU microcode, as LVI necessitates expensive software updates to serialize the processor pipeline and disable speculation after potentially every load operation. LVI unifies the transient-execution research landscape by applying gadget-driven techniques from the Spectre world to reversely exploit prior Meltdown-type data leakages. We show that LVI is especially relevant in the context of Intel SGX, where LVI may arbitrarily hijack transient execution in a victim enclave and ultimately leak arbitrary secrets, breaking confidentiality guarantees in the Intel SGX ecosystem (see "What is Intel SGX" below). LVI bypasses all existing mitigations against transient-execution attacks, such as Meltdown, Spectre, Foreshadow, ZombieLoad, RIDL, and Fallout. ![]() Among Atom processors, only older Silvermont/Airmont (without SGX support) are potentially affected. We found that some other recent, acclaimed Meltdown-resistant recent Core-family processors are only potentially vulnerable to LVI-zero-data (aka loads exhibiting zero injection behavior only). The most recent Icelake Core-family processors appear unaffected by LVI. SGX is supported on certain Core-family processors from Skylake onwards. Intel provides a list with all affected products here. As such, in our current assessment, you should consider LVI and install updates if you are using a recent processor equipped with Intel SGX technology (see "What is Intel SGX" below). We believe that LVI is principally relevant as an attack by a malicious compromised operating system or hypervisor targeting Intel SGX enclaves.
