Known vulnerabilities and defects
- 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.
- TSX Asynchronous Abort (ZombieLoad v2) (CVE-2019-11135): Aborted TSX transactions leak data from microarchitectural buffers, including on parts that fixed MDS.
- Downfall / Gather Data Sampling (CVE-2022-40982): The AVX gather instruction leaks stale data from internal vector registers.
