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