Microsoft Windows kernel user mode privilege escalation
| win-kernel-usermode-priv-escalation (53546) |  High Risk |
Description:
Microsoft Windows kernel could allow a local attacker to gain elevated privileges on the system, caused by a NULL pointer dereference error when certain data is passed from user mode. By persuading a victim to browse a directory containing a specially-crafted application, an attacker could exploit this vulnerability to execute arbitrary code with kernel privileges or cause the system to crash.
