  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\niio: accel: bmc150: Fix irq assumption regression\n\nThe code in bmc150-accel-core.c unconditionally calls\nbmc150_accel_set_interrupt() in the iio_buffer_setup_ops,\nsuch as on the runtime PM resume path giving a kernel\nsplat like this if the device has no interrupts:\n\nUnable to handle kernel NULL pointer dereference at virtual\n  address 00000001 when read\n\nPC is at bmc150_accel_set_interrupt+0x98/0x194\nLR is at __pm_runtime_resume+0x5c/0x64\n(...)\nCall trace:\nbmc150_accel_set_interrupt from bmc150_accel_buffer_postenable+0x40/0x108\nbmc150_accel_buffer_postenable from __iio_update_buffers+0xbe0/0xcbc\n__iio_update_buffers from enable_store+0x84/0xc8\nenable_store from kernfs_fop_write_iter+0x154/0x1b4\n\nThis bug seems to have been in the driver since the beginning,\nbut it only manifests recently, I do not know why.\n\nStore the IRQ number in the state struct, as this is a common\npattern in other drivers, then use this to determine if we have\nIRQ support or not.",
