CVE-2023-32674

Local availability loss via undisclosed buffer overflow

Published Jun 12, 2023 · Updated Jan 3, 2025

Buffer overflow in HP PC Hardware Diagnostics Windows before 2.4.0.0 allows local users to interrupt the diagnostic application. HP has not published the affected component, the input that reaches it, or the unchecked copy operation that overruns its destination buffer. Exploitation requires local low-privileged access and is limited by HP's published vector to availability loss, with no confidentiality or integrity impact.
