CVE-2025-71193

Boot crash via premature runtime PM enablement

Published Feb 4, 2026 · Updated Feb 4, 2026

NULL pointer dereference in the Linux kernel QCOM QUSB2 PHY driver from 4.17 causes a sporadic crash during system boot. The probe path enables runtime power management before storing the QPHY instance as driver data, so an early suspend callback dereferences NULL. The failure requires an affected Qualcomm QUSB2 PHY platform and the narrow probe-time suspend window; the documented consequence is a boot-time service interruption, with no published external trigger.
