Vulnerability Information

Windows Secure Kernel Mode Information Disclosure Vulnerability CVE-2016-3256

An information disclosure vulnerability exists when Windows Secure Kernel Mode
improperly handles objects in memory. A locally-authenticated attacker who 
successfully exploited this vulnerability could be able to read sensitive 
information on the target system.

application on the target system. Note that the information disclosure 
vulnerability by itself would not be sufficient for an attacker to compromise
a system. However, an attacker could combine this vulnerability with 
additional vulnerabilities to further exploit the system. The update addresses
the vulnerability by correcting how Windows Secure Kernel Mode handles objects
in memory.
