Potential Time-of-Check to Time-of Use (TOCTOU) vulnerabilities have been identified in the HP BIOS for certain HP PC products which may allow arbitrary code execution, denial of service, and information disclosure.

Weakness

The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
