Privileged memory disclosure via SMM out-of-bounds read
Published May 15, 2026 · Updated May 15, 2026
Improper input validation in affected AMD processors allows local privileged attackers to read out-of-bounds SMM memory. The AMD OverDrive module in System Management Mode fails to validate an input before using it for a memory read beyond the intended bounds. Exploitation requires high local privileges and no user interaction, and the resulting access exposes data without reported modification or service interruption.
