CVE-2023-34351Network attack vector

Service crash via undisclosed buffer underflow

Published Feb 14, 2024 · Updated Aug 7, 2024

Buffer underflow in Intel Performance Counter Monitor before 202307 allows remote attackers to crash the service via network access. Intel identifies the weakness as a buffer underwrite but has not disclosed the affected component, input field, or faulty buffer operation. No authentication or user interaction is required, and the published impact is limited to service interruption rather than data exposure or modification.
