CVE-2023-45733

What it actually does

Race conditions in processor hardware logic allow a local authenticated user to observe partial unauthorized data through timing or state inconsistencies during concurrent operations.

Why it matters to the business

Limited risk of sensitive data leakage on affected systems requiring local access and specific conditions, with low likelihood of widespread operational disruption.

How an attack unfolds

An attacker with local authenticated access triggers concurrent hardware operations that expose partial internal processor state or data due to unsynchronized logic paths.

How to fix it

Apply the latest Intel microcode updates and firmware releases addressing the processor logic issue; monitor vendor advisories for affected models and schedule updates during maintenance windows.

How to confirm the fix worked

Confirm microcode and firmware versions match or exceed vendor-recommended fixes for the processor model; retest under concurrent workloads to verify absence of observable leakage.

Typical attack path

1. Obtain local authenticated access on a system with an affected Intel processor
2. Identify or craft workloads that induce concurrent hardware operations prone to the race condition
3. Observe timing or side-channel artifacts to extract partial unauthorized information

How to detect it

Hardware-level races are difficult to detect post-exploitation; review system logs for unusual local access patterns or side-channel activity on affected hardware if telemetry is available.

What your security team should do

• Inventory systems using affected Intel processors and prioritize microcode/firmware updates
• Enforce least-privilege local access controls to reduce attack surface
• Monitor Intel security advisories for additional processor-specific guidance
