CVE-2022-23957

Local service interruption

Published Mar 2, 2022 · Updated Aug 3, 2024

Denial of service in the BIOS of some HP PC products allows local users with low privileges to cause a system service interruption. HP has not published the affected BIOS component, malformed input, incorrect operation, or whether exploitation causes a hang, crash, or reboot. Local low-privileged access is required, and the documented impact is limited to availability loss without reported data disclosure or modification.
