An issue in “Zen 2” CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive information.

Security readout for executives and security teams

CVE-2023-20593 affects several AMD Zen 2 processor families and may let an attacker access sensitive information from CPU behavior. The main business risk is data exposure on affected endpoints, servers, or shared compute where untrusted code can run. Organizations may be exposed if they operate listed AMD Zen 2 systems, especially 2nd Gen EPYC servers, virtualization hosts, or user-accessible workstations where untrusted local workloads can execute. Prioritize servers, virtualization platforms, and shared workstations first because the issue concerns potential sensitive information exposure at the CPU level. Treat remediation as high priority, paced by OEM firmware availability. Mitigation focus: Inventory systems using affected AMD Zen 2 processors.; Apply AMD-recommended microcode or AGESA firmware updates from OEMs.; Apply relevant OS microcode packages and security updates..
