CVE-2022-27170

What it actually does

Protection mechanism failure in Intel Media SDK allows an authenticated local user to bypass intended access controls and escalate privileges on the host system.

Why it matters to the business

Local attackers can gain elevated control over systems running the affected SDK, increasing risk of unauthorized data access, persistence, or lateral movement; the issue has been public for over three years with negligible exploit activity.

How an attack unfolds

An attacker with a valid local account on a system using vulnerable Intel Media SDK software triggers the flawed protection logic through normal SDK usage to obtain higher privileges.

How to fix it

Upgrade Intel Media SDK to version 22.2.2 or later on all affected systems; where upgrades are not feasible, restrict local access and monitor for anomalous privilege changes.

How to confirm the fix worked

Verify the installed Intel Media SDK version is 22.2.2 or newer; confirm the vulnerable component is no longer present via package inventory or vendor tooling.

Typical attack path

1. Gain local authenticated access to a target system
2. Execute or load a process that invokes the Intel Media SDK
3. Abuse the protection mechanism failure to escalate to higher privileges

How to detect it

Search system and application logs for unexpected privilege changes or new high-privilege processes launched shortly after media SDK activity; correlate with authentication events.

What your security team should do

• Prioritize inventory of systems using Intel Media SDK and schedule upgrades to 22.2.2+
• Apply least-privilege principles for local accounts that interact with media processing workloads
• Review and harden local access controls on development and media-encoding endpoints
