fix(PeriphDrivers): Fix `MXC_SYS_GetUSN` Buffer Overflow

Open Jake-Carter opened this issue 9 months ago • 0 comments

Description

Fixes #1006

This PR updates MXC_SYS_GetUSN to prevent buffer overflow. The application-side buffer should be MXC_SYS_USN_LEN, but we were using MXC_SYS_USN_CHECKSUM_LEN which is a larger buffer size with some additional padding used for the internal CRC calculation.
