CVE-2020-0534Network attack vector

Unauthenticated service interruption via undisclosed DAL input

Published Jun 15, 2020 · Updated Aug 4, 2024

Improper input validation in Intel CSME DAL before 12.0.64, 13.0.32, 14.0.33, and 14.5.12 allows remote attackers to cause a service interrupt. Intel has not published the affected DAL parser, the untrusted input it accepts, or the invalid operation that triggers the failure. Network access without authentication is sufficient; the published impact is limited to loss of availability, but Intel does not specify whether CSME hangs, crashes, or reboots.
