CVE-2026-122113 (GCVE-0-2026-122113)

Vulnerability from cvelistv5 – Published: 2026-11-06 18:36 – Updated: 2026-11-10 18:21

Title

CVE-2026-122113

Summary

A vulnerability in Realtek's RtUsbA64.sys USB audio driver allows a physically present attacker using a maliciously crafted USB device to trigger unbounded recursion in the driver's topology-parsing logic during device enumeration. Processing the crafted descriptor exhausts the kernel stack and causes a system crash (bugcheck), resulting in a denial of service. No authenticated user session is required.

Severity

4.3 (Medium)

CVE-2026-90975 (GCVE-0-2026-90975)

Vulnerability from cvelistv5 – Published: 2026-11-06 18:36 – Updated: 2026-11-10 18:23

Title

CVE-2026-90975

Summary

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.
