The mpi_powm function in lib/mpi/mpi-pow.c in the Linux kernel up to and including 4.8.11 does not ensure that memory is allocated for limb data, which allows local users to cause a denial of service (stack memory corruption and panic) via an add_key system call for an RSA key with a zero exponent.
