Realtek HD Audio Codec Driver IOCTL requests privilege escalation
| realtek-ioctl-privilege-escalation (41976) |  High Risk |
Description:
Multiple Realtek HD Audio Codec Drivers could allow a local attacker to gain elevated privileges on the system, caused by improper validation of user-supplied input when handling IOCTL requests. By sending a specially-crafted IOCTL request, a local authenticated attacker could exploit this vulnerability to create, read or write arbitrary code on the system with SYSTEM level privileges.
