CVE-2026-13585 is a local vulnerability in the ASUS System Control Interface driver and ASUS Business Manager, including affected ASUS System Control Interface v3 releases before 3.1.66.0, ASUS System Control Interface releases before 1.1.40.0, and ASUS Business Manager through 3.0.38.0. The issue is described as a combination of allocation of resources without limits or throttling and failure to remove sensitive information from a resource before reuse. The vulnerable attack surface is exposed through crafted IOCTL requests to the driver. Available reporting also characterizes the flaw in the affected driver as involving unvalidated IOCTL handling that can enable arbitrary physical memory mapping. Exploitation by a local administrator can disclose sensitive information from kernel-managed resources and, in more severe cases, destabilize the system and trigger denial of service.
