Summary
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)
