A whole sequence of Rear Hazcam images with salt and pepper noise.

Technically this isn't salt and pepper noise because there are no dark pixels, only bright ones. (No pepper, only salt.) So these are unlikely to be transmission errors (they couldn't be anyway because image compression causes transmission errors to look completely different) but hot pixels. Hot pixels are worse with longer exposure and with higher camera head temperature.
As noted the rear hazcams are closer to the RTG and also to the other neutron source on the rover, DAN.
