The issue arises from improper validation of certain parameters to hooked System Service Descriptor Table (SSDT) functions. This can be exploited by local users to cause a denial of service, resulting in a system crash. The exploitation vectors include a crafted `OBJECT ATTRIBUTES` structure in a call to the `NtDeleteFile` function, leading to improper validation of a `ZwQueryObject` result, as well as unspecified calls to the `NtCreateFile` and `NtSetThreadContext` functions.
