Weaknesses
CWE · root cause- CWE-1342Information Exposure through Microarchitectural State after Transient ExecutionThe processor does not properly clear microarchitectural state after incorrect microcode assists or speculative execution, resulting in transient execution.
- CWE-203Observable DiscrepancyThe product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor.
Affected systems
Known conditions: local access, low-privilege account, no user interaction (CVSS vector). Other conditions: not stated in public data.
