Speculative execution branch target injectionAn industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions . There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant CVE-2017-5715 triggers the speculative execution by utilizing branch target injection. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor#039;s data cache even for speculatively executed instructions that never actually commit . As a result, an unprivileged attacker could use this flaw to cross the syscall and guest/host boundaries and read privileged memory by conducting targeted cache side-channel attacks.
