CVE-2023-22995

Local system crash via device-registration resource leak

Published Feb 28, 2023 · Updated May 5, 2025

Memory leak in the Qualcomm DWC3 USB driver in Linux kernels before 5.17 allows local users to crash the system during device registration. The dwc3_qcom_acpi_register_core function exits from allocation and device-addition error paths without releasing the allocated platform device. Exploitation requires local access and execution of the Qualcomm DWC3 ACPI registration error path; the reported consequence is a system crash.
