| Date discovered | March 2020 |
| Affected hardware | Intel x86 microprocessors |
| Website | lviattack |
Load value injection (LVI) is an attack on Intel microprocessors that can be used to attack Intel's SGX technology.[1] It is a development of the previously known Meltdown security vulnerability. Unlike Meltdown, which can only read hidden data, LVI can inject data values, and is resistant to the countermeasures so far used to mitigate the Meltdown vulnerability.[2][3]
As of March 2020[update], LVI is only known to affect Intel microprocessors.[2] Intel has published a guide to mitigating the vulnerability by using compiler technology, requiring existing software to be recompiled to add load barriers at every potentially vulnerable point in the code.[4]
