CVE-2025-37842Public exploit

Kernel panic via premature legacy driver removal

Published May 9, 2025 · Updated May 11, 2026

Denial of service in the Linux fsl-qspi driver allows local users to panic the kernel by unbinding an i.MX8MQ SPI device. The driver mixes device-managed APIs with a legacy remove callback, so detach invokes manual removal before device-managed cleanup and violates the release sequence. Access to the privileged sysfs driver-unbind control on a system with the fsl-quadspi device is required; detaching it crashes the host.
