Sensitive-memory disclosure via ASP out-of-bounds read
Published Sep 6, 2025 · Updated Sep 8, 2025
An out-of-bounds read in the AMD Secure Processor on affected Ryzen and Athlon processors allows privileged attackers to read sensitive memory. AMD identifies the ASP and out-of-bounds operation but has not disclosed the affected routine, buffer, or missing bounds check. Exploitation requires high local privileges and control of a malicious bootloader; the reported consequence is limited to confidentiality loss.
