Vulnerability Information

Windows NDIS Elevation of Privilege Vulnerability – CVE-2015-6098

An elevation of privilege vulnerability exists when NDIS fails to check the length of a buffer prior to copying memory into it. An attacker who successfully exploited this vulnerability could gain elevated privileges on a targeted system.

To exploit the vulnerability, an attacker would first have to log on to the system. The attacker could then run a specially crafted application designed to elevate privileges. The security update corrects how NDIS validates buffer length.

Microsoft received information about this vulnerability through coordinated vulnerability disclosure. At the time this security bulletin was originally issued, Microsoft was unaware of any attack attempting to exploit this vulnerability.
