The vulnerability allows a local user to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in igdkmd64.sys for several Intel Graphics Drivers. A local user can send a specially crafted HTTP request and read arbitrary files on the system, leading to escalation of privilege or denial of service.
