A potential security vulnerability has been identified in the System BIOS for some HP PC products which may allow escalation of privilege, arbitrary code execution, denial of service, or information disclosure via a physical attack that requires specialized equipment and knowledge. HP is releasing firmware mitigation for the potential vulnerability.
The product provides software-controllable device functionality for capabilities such as power and clock management, but it does not properly limit functionality that can lead to modification of hardware memory or register bits, or the ability to observe physical side channels.
