CVE-2015-0058 is a double-free vulnerability in the Windows kernel-mode driver win32k.sys, referred to by Microsoft as the Windows Cursor Object Double Free Vulnerability. The flaw affects Microsoft Windows 8.1, Windows Server 2012 R2, and Windows RT 8.1. According to the provided content, improper handling of a cursor object can cause the same memory to be freed twice in kernel context. A local attacker can trigger the condition via a crafted application after logon. Microsoft bulletin 3036220 identifies this as a Win32k issue in the kernel-mode graphics subsystem.
