CVE-2017-12193

A flaw was found in the Linux kernel's implementation of associative arrays introduced in 3.13. This functionality was backported to the 3.10 kernels in Red Hat Enterprise Linux 7. The flaw involved a null pointer dereference in assoc_array_apply_edit() due to incorrect node-splitting in assoc_array implementation. This affects the keyring key type and thus key addition and link creation operations may cause the kernel to panic.

This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5 and 6.

This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 7,MRG-2 and realtime kernels. Future Linux kernel updates for the respective releases may address this issue.
