Vulnerability Name:

CVE-2016-8650 (CCN-119408)

Assigned:2016-11-15
Published:2016-11-15
Updated:2023-02-12
Summary: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.
