CVE-2026-15030 in System Control Interface
Summary
by MITRE • 07/15/2026
Out-of-bounds Read in ASUS System Control Interface v3, ASUS System Control Interface, and ASUS Business Manager allows a local administrator to read memory regions beyond the intended firmware boundary by supplying a crafted IOCTL request that bypasses the validation. Refer to the ' Security Update for ASUS System Control Interface ' section on the ASUS Security Advisory for more information.

This vulnerability represents a critical out-of-bounds read flaw affecting ASUS System Control Interface versions 3, ASUS System Control Interface, and ASUS Business Manager software components. The issue stems from insufficient input validation within the device driver layer that handles IOCTL (Input/Output Control) requests used for system-level communication between user-space applications and kernel-mode drivers. When a local administrator submits a specially crafted IOCTL request, the system fails to properly bounds-check the input parameters against the allocated memory boundaries, allowing arbitrary memory access beyond intended firmware limits.
The technical implementation of this vulnerability resides in the kernel-mode driver component responsible for processing system control interface requests. The flaw manifests when the driver receives an IOCTL command with malformed parameter structures that exceed expected buffer sizes. According to CWE-129, this represents an implementation weakness where insufficient validation of input data leads to memory access violations. The vulnerability operates at the intersection of privilege escalation and information disclosure categories since it requires local administrative privileges but can expose sensitive system memory contents to unauthorized reading.
From an operational perspective, this vulnerability creates significant security implications for organizations relying on ASUS system management interfaces. The local administrator privilege requirement means that an attacker with access to a legitimate administrative account could potentially extract sensitive information from kernel memory regions including system configuration data, credential storage locations, or other confidential information. This type of vulnerability aligns with ATT&CK technique T1059.003 for command and scripting interpreter usage in conjunction with privilege escalation pathways.
The impact extends beyond simple information disclosure as the read operation could potentially expose memory addresses, kernel structures, or sensitive data that might aid in further exploitation attempts. Attackers could leverage this vulnerability to discover system internals that would otherwise remain hidden, providing valuable reconnaissance information for more sophisticated attacks including potential kernel exploitation or credential harvesting operations. Organizations should note that while the initial privilege requirement limits immediate exploitation, it does not eliminate the risk of escalation through additional attack vectors.
Mitigation strategies include applying the official ASUS security patches referenced in their advisory documentation, which typically involve implementing proper bounds checking and input validation within the IOCTL handling routines. System administrators should also consider restricting administrative access to minimize potential attack surfaces and implement monitoring for unusual IOCTL activity patterns that might indicate exploitation attempts. The vulnerability demonstrates the importance of defensive programming practices and adheres to security principles outlined in NIST SP 800-53 controls related to input validation and memory protection mechanisms.
