ASUS System Control Interface Memory and Resource Flaws

Arbitrary physical memory read/write in the ASUS System Control Interface (v3 and legacy) and ASUS Business Manager driver allows a local administrator to issue crafted IOCTL requests that bypass OS-enforced memory protections, per an ASUS-published advisory. The flaw (CWE-822, Untrusted Pointer Dereference) turns the signed ASUS driver into a read/write primitive over physical memory, enabling privilege escalation from admin to kernel and potential defense evasion. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV; EPSS was not provided.

Local information disclosure and denial of service in the ASUS System Control Interface driver (v3 and earlier) and ASUS Business Manager lets a user already holding local administrator rights issue crafted IOCTL requests to read leftover sensitive data from kernel/driver buffers and, in severe cases, exhaust unthrottled resources to crash the host. The flaw stems from missing resource limits (CWE-770) combined with reuse of memory that still contains prior sensitive contents. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV; ASUS self-reported and issued an advisory.

Out-of-bounds memory read in ASUS System Control Interface v3, ASUS System Control Interface, and ASUS Business Manager exposes kernel and firmware memory contents to local administrators via a crafted IOCTL request that bypasses the driver's length validation. The vulnerability (CWE-125) is constrained to AV:L/PR:H, meaning exploitation requires prior establishment of local administrator access on a system where the affected ASUS software is installed. No public exploit code or active exploitation has been confirmed at time of analysis; the ASUS Security Advisory documents the remediation path.
