CVE-2026-75809: CWE-782: Exposed IOCTL with Insufficient Access Control in ASUS Armoury Crate
CVE-2026-75809 is a medium severity vulnerability in ASUS Armoury Crate involving an exposed IOCTL interface with insufficient access control. This flaw allows a local user to bypass driver authentication and use IOCTL commands to read from and write to PCIe configuration space, potentially disclosing information and disabling device functionality. No patch or official remediation guidance has been provided yet.
AI Analysis
Technical Summary
The vulnerability CVE-2026-75809 in ASUS Armoury Crate is due to an exposed IOCTL interface that lacks sufficient access control. A local attacker can bypass driver authentication mechanisms and invoke IOCTLs to access PCIe configuration space for reading and writing. This can lead to information disclosure and disruption of device functionality. The CVSS 4.0 score is 5.9 (medium severity), reflecting the local attack vector with high attack complexity and privileges required. No vendor advisory or patch information is currently available.
Potential Impact
A local attacker with low privileges can exploit this vulnerability to bypass driver authentication and manipulate PCIe configuration space via IOCTL calls. This can result in unauthorized information disclosure and potentially disabling device functionality, impacting system stability and security.
Mitigation Recommendations
Patch status is not yet confirmed — check the ASUS Security Advisory for Armoury Crate for current remediation guidance. Until an official fix is released, restrict local access to trusted users only to reduce risk.
