CVE-2023-1048

A vulnerability, which was classified as critical, has been found in TechPowerUp Ryzen DRAM Calculator 1.2.0.5. This issue affects some unknown processing in the library WinRing0x64.sys. The manipulation leads to improper initialization. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-221807.

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.
