It was discovered that a double free existed in the AMD GPIO driver in the
Linux kernel. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2017-18174)
It was discovered that an integer overrun vulnerability existed in the
POSIX timers implementation in the Linux kernel. A local attacker could use
this to cause a denial of service. (CVE-2018-12896)
Kanda Motohiro discovered that writing extended attributes to an XFS file
system in the Linux kernel in certain situations could cause an error
condition to occur. A local attacker could use this to cause a denial of
service. (CVE-2018-18690)
It was discovered that an integer overflow vulnerability existed in the
CDROM driver of the Linux kernel. A local attacker could use this to expose
sensitive information (kernel memory). (CVE-2018-18710)");
