Dell BIOS contains a race condition vulnerability. A local attacker could exploit this vulnerability by sending malicious input via SMI in order to bypass security checks during SMM.
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.
