Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> gpio: davinci: Validate the obtained number of IRQs<br /> <br /> Value of pdata-&gt;gpio_unbanked is taken from Device Tree. In case of broken<br /> DT due to any error this value can be any. Without this value validation<br /> there can be out of chips-&gt;irqs array boundaries access in<br /> davinci_gpio_probe().<br /> <br /> Validate the obtained nirq value so that it won&amp;#39;t exceed the maximum<br /> number of IRQs per bank.<br /> <br /> Found by Linux Verification Center (linuxtesting.org) with SVACE.
