CVE-2022-29919
📋 TL;DR
CVE-2022-29919 is a use-after-free vulnerability in Intel VROC (Virtual RAID on CPU) software that allows authenticated local users to potentially escalate privileges. This affects systems running Intel VROC software before version 7.7.6.1003. The vulnerability requires local access and authentication to exploit.
💻 Affected Systems
- Intel Virtual RAID on CPU (VROC) software
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker gains full system administrator privileges, potentially compromising the entire system and accessing sensitive data.
Likely Case
Privileged local user escalates to higher privileges, enabling unauthorized system modifications or data access.
If Mitigated
With proper access controls and patching, the attack surface is limited to authorized users only, reducing overall risk.
🎯 Exploit Status
Requires local authenticated access. No public exploit code available at time of advisory.
