CVE-2014-3690

Priority
Description
arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.17.2
on Intel processors does not ensure that the value in the CR4 control
register remains the same after a VM entry, which allows host OS users to
kill arbitrary processes or cause a denial of service (system disruption)
by leveraging /dev/kvm access, as demonstrated by PR_SET_TSC prctl calls
within a modified copy of QEMU.
Ubuntu-Description
A flaw was discovered in how the Linux kernel's KVM (Kernel Virtual
Machine) subsystem handles the CR4 control register at VM entry on Intel
processors. A local host OS user can exploit this to cause a denial of
service (kill arbitrary processes, or system disruption) by leveraging
/dev/kvm access.
Notes
jdstrandandroid kernels (flo, goldfish, grouper, maguro, mako and manta) are
not supported on the Ubuntu Touch 14.04 preview kernels
linux-lts-saucy no longer receives official support
