CVE-2020-1027: high-severity vulnerability in Microsoft Windows

A flaw in how Windows Kernel manages memory objects allows an attacker with limited access to gain elevated privileges and control the system. This is a serious vulnerability because it can let unauthorized users take full control of a computer.

An out-of-bounds write vulnerability in Windows Kernel's object handling enables local privilege escalation. An attacker with local user-level access can exploit improper memory management to overwrite kernel structures and achieve SYSTEM privileges. Exploitation requires local code execution capability but no special user rights beyond standard account access.
