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."

Esto permite a usuarios locales (con acceso a /dev/video0) obtener permisos de lectura y escritura en las p\u00e1ginas f\u00edsicas del kernel, lo que posiblemente puede resultar en una escalada de privilegios."
