Description
In the Linux kernel, the following vulnerability has been resolved: pinctrl: at91: Fix possible out-of-boundary access at91_gpio_probe() doesn't check that given OF alias is not available or something went wrong when trying to get it. This might have consequences when accessing gpio_chips array with that value as an index. Note, that BUG() can be compiled out and hence won't actually perform the required checks.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability in the Linux kernel's pinctrl at91 driver occurs because the function at91_gpio_probe() does not properly check if a given OF alias is available or if an error occurred when retrieving it. This can lead to an out-of-boundary access when using the alias value as an index into the gpio_chips array. Additionally, the BUG() macro that would normally enforce checks can be compiled out, removing safeguards against this issue.


How can this vulnerability impact me? :

The vulnerability can cause out-of-boundary memory access, which may lead to system instability, crashes, or potentially allow an attacker to execute arbitrary code or cause denial of service by exploiting the improper bounds checking in the gpio_chips array indexing.
