Administrator memory disclosure via unchecked IOCTL bounds

Published Jul 15, 2026 · Updated Jul 15, 2026

Out-of-bounds read in ASUS System Control Interface and Business Manager allows local users with administrator rights to disclose firmware memory. The Windows driver accepts a crafted IOCTL request that bypasses boundary validation and reads memory beyond the intended firmware region. Local access and administrator rights are required; the published impact is limited to disclosure, with no integrity or availability effect.
