  script_tag(name:"insight", value:"It was discovered that the nested KVM implementation in the Linux kernel in
some situations did not properly prevent second level guests from reading
and writing the hardware CR8 register. A local attacker in a guest could
use this to cause a denial of service (system crash). (CVE-2017-12154)

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)

It was discovered that a race condition existed in the ALSA subsystem of
the Linux kernel when creating and deleting a port via ioctl(). A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2017-15265)

It was discovered that a null pointer dereference vulnerability existed in
the DCCP protocol implementation in the Linux kernel. A local attacker
could use this to cause a denial of service (system crash). (CVE-2018-1130)

Julian Stecklina and Thomas Prescher discovered that FPU register states
(such as MMX, SSE, and AVX registers) which are lazily restored are
potentially vulnerable to a side channel attack. A local attacker could use
this to expose sensitive information. (CVE-2018-3665)

Wang Qize discovered that an information disclosure vulnerability existed
in the SMBus driver for ACPI Embedded Controllers in the Linux kernel. A
local attacker could use this to expose sensitive information (kernel
pointer addresses). (CVE-2018-5750)

It was discovered that the SCTP Protocol implementation in the Linux kernel
did not properly validate userspace provided payload lengths in some
situations. A local attacker could use this to cause a denial of service
(system crash). (CVE-2018-5803)

It was discovered that an integer overflow error existed in the futex
implementation in the Linux kernel. A local attacker could use this to
cause a denial of service (system crash). (CVE-2018-6927)

It was discovered that an information leak vulnerability existed in the
floppy driver in the Linux kernel. A local attacker could use this to
expose sensitive information (kernel memory). (CVE-2018-7755)

It was discovered that a memory leak existed in the SAS driver subsystem of
the Linux kernel. A local attacker could use this to cause a denial of
service (memory exhaustion). (CVE-2018-7757)");
