CVE-2017-7518

Priority
Description
A flaw was found in the Linux kernel before version 4.12 in the way the KVM
module processed the trap flag(TF) bit in EFLAGS during emulation of the
syscall instruction, which leads to a debug exception(#DB) being raised in
the guest stack. A user/process inside a guest could use this flaw to
potentially escalate their privileges inside the guest. Linux guests are
not affected by this.
Ubuntu-Description
Andy Lutomirski discovered that the KVM implementation in the Linux kernel
was vulnerable to a debug exception error when single-stepping through a
syscall. A local attacker in a non-Linux guest vm could possibly use this
to gain administrative privileges in the guest vm.
