Memory Corruption Vulnerability in Linux Kernel's mpi_powm Function

CVE-2016-8650 · MEDIUM Severity

AV:L/AC:L/AU:N/C:N/I:N/A:C

The mpi_powm function in lib/mpi/mpi-pow.c in the Linux kernel through 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.
