AMD has quietly removed Transparent Secure Memory Encryption (TSME) from its consumer Ryzen CPUs without warning, a security feature that previously protected against physical memory attacks. The change, which was discovered by a Linux user and confirmed by AMD, makes the encryption feature exclusive to PRO-series processors. This move has raised concerns among security-conscious users who relied on this protection against cold boot attacks and other physical exploits.
