A vulnerability in Realtek's RtUsbA64.sys USB audio driver allows a local, low-privileged user to abuse a kernel I/O control (IOCTL) interface that acts on a caller-supplied user-mode pointer without proper validation or capture. By issuing crafted property requests an attacker can obtain kernel-mode read and write access, which can be leveraged for local privilege escalation and arbitrary kernel code execution.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
