CVE-2023-22444

Improper initialization in some Intel(R) NUC 13 Extreme Compute Element, Intel(R) NUC 13 Extreme Kit, Intel(R) NUC 11 Performance Kit, Intel(R) NUC 11 Performance Mini PC, Intel(R) NUC Compute Element, Intel(R) NUC Laptop Kit, Intel(R) NUC Pro Kit, Intel(R) NUC Pro Board and Intel(R) NUC Pro Mini PC BIOS firmware may allow a privileged user to potentially enable information disclosure 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.

Affected Software

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.
