In the Linux kernel, the following vulnerability has been resolved:
iio: imu: adis: Fix NULL pointer dereference in adis_init
The adis_init() function dereferences adis->ops to check if the
individual function pointers (write, read, reset) are NULL, but does
not first check if adis->ops itself is NULL.
Drivers like adis16480, adis16490, adis16545 and others do not set
custom ops and rely on adis_init() assigning the defaults. Since struct
adis is zero-initialized by devm_iio_device_alloc(), adis->ops is NULL
when adis_init() is called, causing a NULL pointer dereference:
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000
pc : adis_init+0xc0/0x118
Call trace:
adis_init+0xc0/0x118
adis16480_probe+0xe0/0x670
Fix this by checking if adis->ops is NULL before dereferencing it,
falling through to assign the default ops in that case.
