Dell PowerEdge Server BIOS and Dell Precision Rack BIOS contain a TOCTOU race condition vulnerability. A local low privileged attacker could potentially exploit this vulnerability to gain access to otherwise unauthorized resources.
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.
