CVE-2025-37811

Kernel crash via optional usbmisc NULL dereference

Published May 8, 2025 · Updated May 23, 2026

NULL pointer dereference in the Linux kernel's i.MX USB driver allows local users to crash affected systems during driver removal. The probe cleanup and removal paths call put_device through data->usbmisc_data without checking whether the optional pointer is NULL. Exploitation requires local access, the i.MX ChipIdea driver without the optional fsl,usbmisc property, and entry into a cleanup path; the reported consequence is limited to a kernel crash.
