Improper initialization in subsystem for Intel(R) CSME versions before12.0.70, 13.0.40, 13.30.10, 14.0.45 and 14.5.25, Intel(R) TXE versions before 4.0.30 Intel(R) SPS versions before E3_05.01.04.200 may allow a privileged user to potentially enable escalation of privilege via local access.
Weakness
The product does not initialize or incorrectly initializes a resource, which might leave the resource in an unexpected state when it is accessed or used.

Potential Mitigations
- Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, in Java, if the programmer does not explicitly initialize a variable, then the code could produce a compile-time error (if the variable is local) or automatically initialize the variable to the default value for the variable’s type. In Perl, if explicit initialization is not performed, then a default value of undef is assigned, which is interpreted as 0, false, or an equivalent value depending on the context in which the variable is accessed.
