DESCRIPTION

* CVE-2018-16658: Information leak in CD-ROM status ioctl.

An incorrect bounds check in the CD-ROM driver could allow an
out-of-bounds access and kernel information leak to an unprivileged
user.


* CVE-2018-7492: Denial-of-service when setting options for RDS over Infiniband socket.

A missing check when setting RDS_GET_MR option for RDS over Infiniband
socket could lead to a NULL pointer dereference. A local attacker could
use this flaw to cause a denial-of-service.
