My colleague Tom O'Connor and I have identified a security bug in the Linux kernel that results in drastically degraded randomness of IP IDs, TCP sequence numbers, and ephemeral port numbers on affected systems. The bug existed in kernel versions 3.13 and 3.14. We are posting here rather than to the private "distros" list because the bug has already been fixed. However, we don't think that the security implications of the bug have been acknowledged anywhere, and we think it needs a CVE. A full write-up on the bug is posted at http://secondlookforensics.com/ngro-linux-kernel-bug/.
I totally agree that this needs a CVE and I thought it was already taken care of by the people on security () kernel org. I am sorry to not have checked for a CVE request afterwards. The corresponding fix is here: <https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3d4405226d27b3a215e4d03cfa51f536244e5de7> Thanks a lot, Hannes
