CVE-2019-18675

The Linux kernel through 5.3.13 has a startoffset+size Integer Overflow in cpia2remapbuffer in drivers/media/usb/cpia2/cpia2core.c because cpia2 has its own mmap implementation. This allows local users (with /dev/video0 access) to obtain read and write permissions on kernel physical pages, which can possibly result in a privilege escalation.
