Three PCIe Encryption Weaknesses Expose PCIe 5.0+ Systems to Faulty Data Handling
Overview
Three vulnerabilities have been found in the PCIe Integrity and Data Encryption (IDE) protocol, affecting systems using PCIe Base Specification Revision 5.0 and newer. These flaws could allow local attackers to manipulate data integrity, leading to potentially serious consequences for the affected systems. The vulnerabilities stem from a new protocol mechanism introduced in a recent engineering change notice, which has not been adequately secured. This issue is particularly concerning for organizations relying on PCIe 5.0+ for high-speed data transfers and secure communications, as they may be at risk of unauthorized data handling. Users and companies should assess their systems for these vulnerabilities and consider implementing security measures to mitigate the risks.
Key Takeaways
- Affected Systems: PCIe Base Specification Revision 5.0 and newer systems
- Action Required: Organizations should review the PCIe IDE protocol specifications and apply any available patches or updates from vendors to mitigate the vulnerabilities.
- Timeline: Newly disclosed
