CVE-2023-27306

Local denial of service via improper initialization

Published Nov 14, 2023 · Updated Aug 2, 2024

Improper initialization in firmware for affected Intel Optane SSD products allows local users to cause a denial of service. Intel has not disclosed the affected firmware locus, the resource initialized incorrectly, or the operation that reaches the invalid state. Low-privilege authenticated local access is required, and the documented consequence is limited to loss of availability; the exact hang, crash, or reset behavior is undisclosed.
