Description OSIDB Bzimport 2025-07-10 08:04:18 UTC 
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.
