Intel® Special Register Buffer Data Sampling Advisory, Disclosed June 9, 2020


Product Information & Documentation



On June 9, 2020, Intel publicly disclosed a potential security vulnerability in some Intel® Processors that may allow information disclosure. Intel has coordinated with industry partners to release microcode updates that address these vulnerabilities.

Special Register Buffer Data Sampling (SRBDS) is similar to previously disclosed transient execution vulnerabilities (MDS, TAA) and independently reported by external researchers, who refer to the issue as CrossTalk.

This vulnerability affects some client and Intel Xeon E3 processors. It does not affect other Intel Xeon Scalable or Intel Atom® processors, or the recently released 10th Gen Core due to different microarchitecture.

Due to its complexity, SRBDS has been classified as medium severity per the industry standard CVSS, and it’s important to note that there are no reports of any real-world exploits of these vulnerabilities.
