An Insufficient Integrity Verification vulnerability in the ASUS ROG peripheral driver installation process allows privilege escalation to SYSTEM. The vulnerability is due to improper access control on the installation directory, which enables the exploitation of a race condition where the legitimate installer is substituted with an unexpected payload immediately after download, resulting in arbitrary code execution. Refer to the "Security Update for ASUS ROG peripheral driver" section on the ASUS Security Advisory for more information.

This medium-severity CVE scores 5.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
