PIC Processor, SPI to microSD card, 25Mhz Clock slew is bad
That waveform doesn’t look too bad - the ringing is normal and isn’t enough to be a false trigger. If it bothers you add a damping resistor at the PIC side of 22-33 ohms. And measure at the SD card itself, not the PIC.
In any event, when taking a scope measurement where signal integrity is a concern, make sure you have a very short ground on scope lead, next to the probe point if possible. This makes a large difference in how much ringing will be present.
