AMD Reinstates Memory Encryption in CPUs
Why It Matters
The removal and subsequent reinstatement of the TSME feature highlights the critical importance of security in consumer technology. Users, especially those in sensitive fields or using Linux systems, depend on such protections to safeguard their data from theft. This incident raises broader concerns about transparency in tech companies' decisions and the potential risks posed to user privacy and safety when crucial security features are altered without notice.
Summary
In June 2026, AMD faced significant backlash after it removed the Transparent Secure Memory Encryption (TSME) feature, also known as Memory Guard, from its consumer CPUs. This security standard, designed to protect against physical data theft, was previously available across both high-end and lower-end AMD processors. The abrupt decision left many users, particularly those using Linux, without adequate protection against potential data breaches. Following widespread criticism and accusations of poor communication, AMD responded by reinstating the TSME feature in its consumer CPUs just a week later. The reinstatement was welcomed by users who rely on this encryption for safeguarding sensitive information, particularly in environments vulnerable to physical attacks.
