LinuxVULNRICHMENT:CVE-2024-42092CVE-2024-42092 gpio: davinci: Validate the obtained number of IRQs
In the Linux kernel, the following vulnerability has been resolved:
gpio: davinci: Validate the obtained number of IRQs
Value of pdata->gpio_unbanked is taken from Device Tree. In case of broken
DT due to any error this value can be any. Without this value validation
there can be out of chips->irqs array boundaries access in
davinci_gpio_probe().
Validate the obtained nirq value so that it won’t exceed the maximum
number of IRQs per bank.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
