CVE-2018-14678 (retired)

Priority
Description
An issue was discovered in the Linux kernel through 4.17.11, as used in Xen
through 4.11.x. The xen_failsafe_callback entry point in
arch/x86/entry/entry_64.S does not properly maintain RBX, which allows
local users to cause a denial of service (uninitialized memory usage and
system crash). Within Xen, 64-bit x86 PV Linux guest OS users can trigger a
guest OS crash or possibly gain privileges.
Ubuntu-Description
M. Vefa Bicakci and Andy Lutomirski discovered that the kernel did not
properly set up all arguments to an error handler callback used when
running as a paravirtualized guest. An unprivileged attacker in a
paravirtualized guest VM could use this to cause a denial of service (guest
VM crash).
