CVE-2025-68330

Estado: AplazadaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

iio: accel: bmc150: Fix irq assumption regression

The code in bmc150-accel-core.c unconditionally calls bmc150_accel_set_interrupt() in the iio_buffer_setup_ops, such as on the runtime PM resume path giving a kernel splat like this if the device has no interrupts:

This bug seems to have been in the driver since the beginning, but it only manifests recently, I do not know why.

Store the IRQ number in the state struct, as this is a common pattern in other drivers, then use this to determine if we have IRQ support or not.
