Descriptions

An issue was discovered in the Linux kernel through 4.19. An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658.

Se ha descubierto un problema en el kernel de Linux hasta la versión 4.19. Una fuga de información en cdrom_ioctl_select_disc en drivers/cdrom/cdrom.c podría ser empleada por atacantes locales para leer memoria del kernel debido a que una conversión de un long no firmado a int interfiere con la comprobación de límites. Esto es similar a CVE-2018-10940 y CVE-2018-16658.
