CVE-2022-50044

Local kernel crash via premature MHI event

Published Jun 18, 2025 · Updated May 11, 2026

Race conditions in the Linux kernel 5.10 through 5.19.3 allow local users to crash the kernel through an early MHI channel event. The qcom_mhi_qrtr_probe function enables automatic MHI transfers before qrtr_endpoint_register creates the endpoint, so the callback can drop an event or dereference an uninitialized endpoint. Reachability requires local low-privileged access and Qualcomm MHI QRTR activity; the observed outcomes are failed service enumeration or a kernel panic.
