CVE-2019-18282

A device tracking vulnerability was found in the flow_dissector feature in the Linux kernel. This flaw occurs because the auto flowlabel of the UDP IPv6 packet relies on a 32-bit hashmd value as a secret, and jhash (instead of siphash) is used. The hashmd value remains the same starting from boot time and can be inferred by an attacker.
