Technical details
This vulnerability is a use-after-free or uninitialized memory disclosure in the ASUS Armoury Crate driver. An attacker with local system access can send a crafted IOCTL (I/O Control) request to the driver that bypasses its security verification mechanism, allowing direct access to uninitialized kernel or driver memory. The vulnerability requires local access and does not require authentication or elevated privileges beyond local user access. An attacker can read sensitive data from memory that should have been cleared before reuse. A security patch is available from ASUS and should be applied immediately.
