CVE-2025-38010

Local suspend disruption via unbalanced UTMI tracking

Published Jun 18, 2025 · Updated May 11, 2026

Denial of service in the Linux kernel allows local users to disrupt system suspension through connected USB devices. The Tegra186 XUSB driver powers down a UTMI pad without checking its state, unbalancing the shared bias_pad_enable reference count. The condition requires Tegra186 XUSB hardware, connected USB devices, and system suspend; it produces kernel warnings and incorrect pad power-state accounting.
