Dell BIOS contains a Time-of-check Time-of-use vulnerability. A local authenticated malicious user couldu00a0potentially exploit this vulnerability by using a specifically timed DMA transaction during an SMI to gain arbitrary code execution on the system.
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.
