CVE-2016-8650 (opens in a new tab)How to fix?
Upgrade Oracle:6 kernel-debug to version 0:2.6.32-754.el6 or higher.
This issue was patched in ELSA-2018-1854.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-debug package and not the kernel-debug package as distributed by Oracle.
See How to fix? for Oracle:6 relevant fixed versions and status.
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.
