Meltdown and Spectre are hardware design vulnerabilities in CPUs utilizing speculative execution.
While the defect exists within the hardware, mitigation in in operation systems are potential and are presently available.
CPU hardware implementations are susceptible to side-channel attacks referred to as Meltdown and Spectre. the problems are organized into 3 variants:
CVE-2017-5753, Spectre Variant 1: CPUs utilizing speculative execution and branch prediction could permitunauthorized revealing of information to an attacker with native user access via a side-channel analysis.
CVE-2017-5715, Spectre Variant 2: Branch target injection
CVE-2017-5754, Meltdown: permits attackers to browse arbitrary physical memory (including kernel memory) from anunprivileged user method.
These attacks are potential owing to the interaction between software package memory management and hardwareimplementation improvement selections.
The UNIX system kernel mitigations for this vulnerability are noted as kaiser, and after KPTI, that aim to enhanceseparation of kernel and user memory pages.
