Microsoft managed to issue a fix for the Windows 11 / Windows Server 2022 encryption vulnerability that makes use of the Vector Advanced Encryption Standard, but the patch is impacting CPU performance. Affected CPUs include Intel’s 10th, 11th, 12th and 13th gen models, while AMD’s affected models include Zen 3 and upcoming Zen 4 processors. Another fix that addresses the performance issues is expected to be available in a month.
This issue is fixed with the May 24, 2022 preview release and the June 14, 2022 security release. However, these updates apparently slow down CPU performance by up to 2x in applications like Bitlocker and Transport Layer Security load balancers. Enterprise customers may also experience slower disk throughput. Performance issues should be fixed with the installation of the June 23, 2022 preview or the July 12, 2022 security release.
