Windows Kernel Remote Code Execution Vulnerability

Use after free in Windows Kernel allows an unauthorized attacker to execute code over a network.

FAQ

How could an attacker exploit the vulnerability?

An attacker could exploit this vulnerability by sending specially crafted network traffic to a vulnerable Windows system. If successful, the malicious network packets could trigger a flaw in how the Windows kernel processes certain TCP/IP data, potentially allowing the attacker to run code with system-level privileges without needing to sign in or interact with a user.
