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.
- Reptar (CVE-2023-23583): Redundant instruction prefixes put the front end into an undefined state, allowing privilege escalation or denial of service.
Matched by codename; individual steppings may differ.
