AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in CPUID cpuz.sys version 1.0.5.4, where an attacker can use specific unvalidated DeviceIoControl parameters to perform RDMSR and WRMSR operations. By doing so, the attacker can modify the MSR_LSTAR register and hook the KiSystemCall64 function. Using Return-Oriented Programming (ROP), the attacker can manipulate the stack, disable the SMAP flag in the CR4 register, and execute a user-mode syscall handler with kernel privileges. This exploit works on 64-bit Windows systems if core isolation is absent or disabled, and it is unclear if it works on 32-bit Windows.
How can this vulnerability impact me? :
This vulnerability allows an attacker to escalate privileges by executing user-mode code with kernel-level privileges, potentially leading to full system compromise. The attacker can manipulate system calls and bypass security features like SMAP, which can result in unauthorized access, data manipulation, or control over the affected system.
