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.
- Special Register Buffer Data Sampling (CrossTalk) (CVE-2020-0543): RDRAND/RDSEED results leak across cores through a shared staging buffer.
- Retbleed (CVE-2022-29901): Return instructions are hijacked through the branch target buffer on cores without enhanced IBRS.
- Downfall / Gather Data Sampling (CVE-2022-40982): The AVX gather instruction leaks stale data from internal vector registers.
