CVE-2015-0057 is a local elevation of privilege vulnerability in the Windows kernel-mode driver Win32k.sys. The flaw is a use-after-free condition in the Win32k User Mode Callback attack surface, described in technical analysis as involving win32k!xxxEnableWndSBArrows and improper handling of objects in memory. Exploitation can be triggered by a crafted local application after logon. Public technical discussion indicates the bug can be transformed into relative heap memory read/write and then arbitrary kernel memory read/write by manipulating Win32k desktop heap objects such as tagPROPLIST, tagWND, and tagMENU. Successful exploitation enables privilege escalation from a local user context to SYSTEM on affected Windows versions.
