# AMD Zen processors: optimization can expose data to a local authorized user

Link for people: https://infrastack.ai/live/CVE-2026-84005 (this .md is for agents)

AMD Zen processors can remove or modify security-critical code through processor optimization, letting an authorized attacker disclose information. The attack is local, so it requires access to the machine first.

_Summary, check and fix written by a model from the sources; labelled as such._
