Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
iio: adc: tsc2046: fix memory corruption by preventing array overflow<br />
<br />
On one side we have indio_dev->num_channels includes all physical channels +<br />
timestamp channel. On other side we have an array allocated only for<br />
physical channels. So, fix memory corruption by ARRAY_SIZE() instead of<br />
num_channels variable.<br />
<br />
Note the first case is a cleanup rather than a fix as the software<br />
timestamp channel bit in active_scanmask is never set by the IIO core.
