use-after-free vulnerability existed in the Netlink subsystem (XFRM) in the
Linux kernel. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2017-16939) It was
discovered that the Linux kernel did not properly handle copy-on- write of
transparent huge pages. A local attacker could use this to cause a denial of
service (application crashes) or possibly gain administrative privileges.
(CVE-2017-1000405) Fan Wu, Haoran Qiu, and Shixiong Zhao discovered that the
associative array implementation in the Linux kernel sometimes did not properly
handle adding a new entry. A local attacker could use this to cause a denial of
service (system crash). (CVE-2017-12193) Eric Biggers discovered that the key
management subsystem in the Linux kernel did not properly restrict adding a key
that already exists but is uninstantiated. A local attacker could use this to
cause a denial of service (system crash) or possibly execute arbitrary code.
(CVE-2017-15299) It was discovered that a null pointer dereference error existed
in the PowerPC KVM implementation in the Linux kernel. A local attacker could
use this to cause a denial of service (system crash). (CVE-2017-15306) Eric
Biggers discovered a race condition in the key management subsystem of the Linux
kernel around keys in a negative state. A local attacker could use this to cause
a denial of service (system crash) or possibly execute arbitrary code.
