CVE-2025-68330

Kernel crash via unconditional interrupt setup

Published Dec 22, 2025 · Updated Dec 22, 2025

NULL-pointer dereference in the Linux BMC150 accelerometer driver allows local users to crash the kernel by enabling its IIO buffer. bmc150_accel_buffer_postenable calls bmc150_accel_set_interrupt unconditionally during buffer setup, dereferencing absent interrupt state on devices with no IRQ support. Reachability requires low-privileged local access and BMC150 hardware configured without interrupts; the resulting fault interrupts service by crashing the kernel.
