AMD silently removes memory encryption from consumer Ryzen CPUs, leaving users unaware that they may be vulnerable — security feature vanishes after newer AGESA firmware, AMD engineers go radio silent when pressed about the change
Summary
Tom's Hardware reports that AMD quietly removed Transparent Secure Memory Encryption from consumer Ryzen CPUs, potentially exposing devices to physical attacks. The story combines Ars Technica reporting with on-record statements from AMD and MSI engineers, highlighting a firmware/policy shift and a lack of official AMD acknowledgement. The practical impact appears limited to consumer chips, with Pro/EPYC SKUs retaining TSME; the piece frames broader questions about hardware security and disclosure.
