CVEID: CVE-2017-2636**
DESCRIPTION:** Linux Kernel could allow a local authenticated attacker to gain elevated privileges on the system, caused by a race condition in the n_hdlc Linux kernel driver (drivers/tty/n_hdlc.c). By using a specially-crafted application, an attacker could exploit this vulnerability to gain privileges on the system.
CVSS Base Score: 7.8

CVEID: CVE-2017-2618**
DESCRIPTION:** Linux Kernel is vulnerable to a denial of service, caused by an off-by-one in the selinux_setprocattr when clearing SELinux attributes on /proc/pid/attr files. A local attacker could exploit this vulnerability using an empty (null) write to cause the system to crash.
CVSS Base Score: 5.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/132346&gt; for the current score
