AMD restores memory encryption to Ryzen 9000 CPUs after community backlash

Feeds.4Sysops •IT News • June 20, 2026

AMD has announced it will reinstate Transparent Secure Memory Encryption (TSME) for consumer-grade Ryzen 9000 desktop processors via a BIOS update in July. This decision follows significant community feedback after the feature was quietly removed in a recent firmware update. TSME, which AMD brands as Memory Guard for its professional product lines, provides a hardware-based layer of protection for data stored in system memory. Source

AMD Firmware Update Exposes Consumers to Memory Attacks AMD has removed the Transparent Secure Memory Encryption (TSME) feature from consumer Ryzen processors via a firmware update, restricting it to Ryzen Pro and EPYC models. This change, which was not communicated to users, leaves many consumer-grade CPUs vulnerable to physical attacks such as cold-boot exploits and memory snooping. The issue was discovered by a security researcher who found that TSME was absent in the latest AGESA firmware version 1.2.7.0. Previously, TSME provided essential encryption to protect data in memory, making it difficult for attackers to access sensitive information. The lack of this feature may significantly impact the security posture of users relying on these processors. AMD has not publicly addressed the controversy in detail, leading to concerns about user trust and potential vulnerabilities. The scope of the impact includes all consumer Ryzen processors that received the update, potentially affecting millions of users. 4 sources 65
