Descriptions

The Linux kernel through 5.3.13 has a start_offset+size Integer Overflow in cpia2_remap_buffer in drivers/media/usb/cpia2/cpia2_core.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.

El kernel de Linux versiones hasta 5.3.13, presenta un desbordamiento de enteros de start_offset+size en cpia2_remap_buffer en el archivo drivers/media/usb/cpia2/cpia2_core.c porque cpia2 posee su propia implementación de mmap. Esto permite a usuarios locales (con acceso a /dev/video0) obtener permisos de lectura y escritura en las páginas físicas del kernel, lo que posiblemente puede resultar en una escalada de privilegios.
