CVE-2025-37901

Kernel crash via non-wake GPIO interrupt setup

Published May 20, 2025 · Updated Aug 5, 2026

Denial of service in the Linux kernel allows local users to crash Qualcomm systems by configuring a non-wake GPIO interrupt. The qcom-mpm driver leaves every GPIO in the MPM IRQ hierarchy and dereferences a nonexistent MPM pin when a GPIO marked GPIO_NO_WAKE_IRQ is requested. Exploitation requires local low-privileged access on a Qualcomm chipset with a non-wake-capable GPIO, and the demonstrated consequence is a kernel crash.
