Описание
Improper isolation of shared resources in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.
A flaw was found in the CPU microarchitecture where a local attacker is able to abuse a timing issue which may allow them to infer internal architectural state from previous executions on the CPU.
