CVE-2020-24452

Authenticated local denial of service

Published Feb 17, 2021 · Updated Aug 4, 2024

Improper input validation in Intel SGX Platform Software before 2.10.100.2 allows local users to cause a service interruption. Intel has not disclosed the affected component, rejected input type, or operation that mishandles the input. Exploitation requires low-privileged local access, and the documented consequence is limited to service interruption rather than data disclosure or modification.
