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.
This was fixed in stable update 4.9.5 which is currently on all supported Fedora releases
