CVE-2020-0586

Local authenticated privilege escalation and service interruption

Published Jun 15, 2020 · Updated Aug 4, 2024

Improper initialization in Intel Server Platform Services firmware allows local authenticated users to escalate privileges or interrupt service. Intel identifies only an unspecified subsystem and has not disclosed which resource is left uninitialized or how local input reaches it. Exploitation requires existing local low-privileged access and can alter protected state or interrupt the platform-management service.
