Ubuntu-Description: It was discovered that the keyring implementation in the Linux kernel improperly handled crypto registration in conjunction with successful key- type registration. A local attacker could use this to cause a denial of service (system crash). 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
