It could occur while doing an ioctl(SIOCADDRT) call on an IPv6 socket. User would need to have CAP_NET_ADMIN privileges to perform such a call. A user/program with CAP_NET_ADMIN privileges could use this flaw to crash a system resulting in DoS. Upstream fix: ------------- -> https://git.kernel.org/linus/ae7b4e1f213aa659aedf9c6ecad0bf5f0476e1e2 Reference: ---------- -> https://bugzilla.redhat.com/show_bug.cgi?id=1039054 Thank you. -- Prasad J Pandit / Red Hat Security Response Team
