CVE-2023-47282

What it actually does

Out-of-bounds write in Intel Media SDK allows local authenticated users to corrupt memory buffers and potentially escalate privileges.

Why it matters to the business

Local users could gain elevated access on systems running affected media processing software, increasing risk of unauthorized actions or further compromise.

How an attack unfolds

An authenticated local attacker supplies crafted input to the media SDK library, triggering the out-of-bounds write to overwrite adjacent memory and elevate privileges without remote access.

How to fix it

Update Intel Media SDK to version 23.3.5 or later; for hamza417/inure apply commit 2176af74ca3a81fd001e6cc8eea5a8306f484fbb.

How to confirm the fix worked

Verify installed Intel Media SDK version is 23.3.5 or newer and confirm the inure repository contains the listed commit hash.

Typical attack path

1. Obtain local authenticated access to the target system
2. Invoke the vulnerable media SDK functions with malicious input
3. Trigger memory corruption to escalate privileges

How to detect it

Look for unexpected crashes or privilege changes in media processing processes and review local access logs for anomalous SDK invocations.

What your security team should do

• Prioritize patching systems with local user access to Intel media components
• Review local privilege boundaries and restrict unnecessary media SDK usage
• Monitor EPSS and exploit maturity for any changes
