A bug in freelist randomization code was found resulting into freelist containing duplicate entries when high random number is used. This will result in different allocations sharing the same chunk which can cause odd behaviours and crashes. This affects kernel versions >= 4.8 when CONFIG_SLAB_FREELIST_RANDOM is enabled. Upstream patch: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c4e490cf148e85ead0d1b1c2caaba833f1d5b29f CVE assignment: http://seclists.org/oss-sec/2017/q1/161
This was fixed in stable update 4.9.5 which is currently on all supported Fedora releases
