Intel processors’ vulnerability, related to the possibility of speculative execution commands, allows attackers to circumvent the memory isolation mechanism of virtual machines.

Intel processors’ vulnerabilities are related to the possibility of speculative execution of instructions. Exploiting these vulnerabilities can allow attackers to gain access to the memory of the supervisor or other virtual machines by overcoming the mechanism that isolates virtual machine memory...
