Nick Peterson discovered that the Linux kernel did not properly handle
debug exceptions following a MOV/POP to SS instruction. A local attacker
could use this to cause a denial of service (system crash). This issue only
affected the amd64 architecture. (CVE-2018-8897)

Andy Lutomirski discovered that the KVM subsystem of the Linux kernel did
not properly emulate the ICEBP instruction following a MOV/POP to SS
instruction. A local attacker in a KVM virtual machine could use this to
cause a denial of service (guest VM crash) or possibly escalate privileges
inside of the virtual machine. This issue only affected the i386 and amd64
architectures. (CVE-2018-1087)

Andy Lutomirski discovered that the Linux kernel did not properly perform
error handling on virtualized debug registers. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2018-1000199)");
