Intel acknowledged that its processors are vulnerable to another dangerous speculative execution side channel flaw that could give attackers unauthorized read access to memory.
The new vulnerability, disclosed by Google Project Zero and Microsoft’s Security Response Center, is called Variant 4, and potentially enables attackers to read privileged data across trust boundaries. That’s similar to two side channel analysis vulnerabilities, Meltdown and Spectre, Intel faced earlier this year in its server and desktop processors.
