CVE-2026-43356

Estado: AnalizadaMedia (5.5)—

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:

Fix this by checking if adis->ops is NULL before dereferencing it, falling through to assign the default ops in that case.
