Executive brief
Windows Secure Kernel Mode is a critical component of Windows that enforces security policies at the kernel level. An authorized attacker can exploit an untrusted pointer dereference vulnerability to escalate their privileges from a limited user account to system-level access, potentially compromising the entire system.
Technical details
The vulnerability is an untrusted pointer dereference flaw in Windows Secure Kernel Mode. The root cause involves improper validation of pointer values before dereferencing them in kernel-mode code. Exploitation requires an attacker to already have local authenticated access to the system. An attacker can craft malicious input to dereference an attacker-controlled pointer, leading to arbitrary code execution at kernel privilege level. Microsoft has issued security patches to address this vulnerability.
