CXL is coming: Are you ready?
Summary
Compute Express Link (CXL) is a new technology set to revolutionize computer architecture by enabling memory disaggregation, persistent memory, and non-uniform memory architectures. It will also standardize the interface between chiplets, leading to improved processor cost/performance and diversity.
IFF Assessment
CXL's advancements in interconnectivity and memory architecture could introduce new attack surfaces and complexities that defenders will need to understand and secure.
Defender Context
As CXL becomes more prevalent, defenders should anticipate new hardware and software vulnerabilities that could arise from its complex interconnectivity and memory management features. Understanding the potential security implications of memory disaggregation and chiplet interfaces will be crucial for developing effective defense strategies.
