The CVE-2025-XXXX vulnerability in Paragon Software products occurs when the kernel-mode driver fails to properly validate the `MappedSystemVa` pointer before passing it to HalReturnToFirmware. This memory address validation flaw allows local attackers to craft malicious pointer values that reference invalid or controlled memory locations. When the driver passes this unvalidated pointer to the firmware return function, it enables arbitrary code execution in kernel context. The vulnerability stems from insufficient input validation in the driver’s memory management routines, specifically when handling mapped system virtual addresses. Attackers can exploit this to escalate privileges, bypass security mechanisms, or cause system crashes.
