Description:
arch/powerpc/kvm/book3s_hv_rmhandlers.S in the Linux kernel through 4.7 on
PowerPC platforms, when CONFIG_KVM_BOOK3S_64_HV is enabled, allows guest OS
users to cause a denial of service (host OS infinite loop) by making a
H_CEDE hypercall during the existence of a suspended transaction.
Ubuntu-Description:
It was discovered that the powerpc and powerpc64 hypervisor-mode KVM
implementation in the Linux kernel for did not properly maintain state
about transactional memory. An unprivileged attacker in a guest could cause
a denial of service (CPU lockup) in the host OS.
Notes:
jdstrand> android kernels (flo, goldfish, grouper, maguro, mako and manta) are
not supported on the Ubuntu Touch 14.10 and earlier preview kernels
jdstrand> linux-lts-saucy no longer receives official support
jdstrand> linux-lts-quantal no longer receives official support
