Is five-volt tolerance guaranteed in Standby / Stop mode?

[C.Ecke]

I want to wake-up from standby mode on a STM32L422xx using PA2 (WKUP4) with pull-down enabled in PWR_PDCRA. Wake-up signal can go up to 5.25V at this pin.

Can this configuration cause any problems e.g. high current injection during wake-up phase?

Thanks in advance.

No issues as long as it's powered appropriately.
