CVE-2015-2360 is a local privilege escalation vulnerability in the Windows Win32k subsystem, specifically in win32k.sys, affecting multiple Microsoft Windows client and server releases including Windows Server 2003, Windows Vista, Windows Server 2008, Windows 7, Windows 8, Windows 8.1, Windows Server 2012, and Windows RT. The flaw is described by Microsoft as a memory corruption issue in kernel-mode drivers that can be triggered by a crafted application. Available technical reporting ties the issue to exploitation of Win32k user-interface object handling and callback-related behavior, where a local process can induce corruption in kernel memory and transition execution into a kernel-privileged context. In observed exploitation, the vulnerability was used to obtain kernel privileges and load or enable unsigned or otherwise unauthorized kernel-mode functionality.
