Known vulnerabilities and defects

  • Meltdown (CVE-2017-5754): Rogue data cache load: user code can read kernel memory through speculative execution.
  • Spectre variant 1 (bounds check bypass) (CVE-2017-5753): Mistrained conditional branches speculatively read out-of-bounds data. Mitigated in software only; every speculative out-of-order core is affected.
  • Foreshadow / L1 Terminal Fault (CVE-2018-3615, CVE-2018-3620, CVE-2018-3646): Speculative reads from the L1 data cache through non-present page table entries, breaking SGX, OS and VMM isolation.
  • Microarchitectural Data Sampling (ZombieLoad, RIDL, Fallout) (CVE-2018-12126, CVE-2018-12127, CVE-2018-12130, CVE-2019-11091): Data in store buffers, fill buffers and load ports leaks across privilege boundaries.
