VOMIT (go/vomit) has received an external vulnerability report for the Linux kernel.
Advisory: CVE-2018-18710
Details: http://vomit.googleplex.com/advisory?id=CVE/CVE-2018-18710
CVSS severity score: 2.1/10.0
Description:
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.

Status: WontFix (was: Untriaged)
Upstream commit e4f3aa2e1e6 ("cdrom: fix improper type cast, which can leat to information leak."). Already fixed in chromeos-{4.4, 4,14, 4,19}. Older kernels are prone to information leaks all over the place, thus WontFix there.
