I bisected the issue with vanilla kernels, and I found the issue seems already fixed in v4.13.14 https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/log/?h=v4.13.14
Could you cherry-pick tun/tap commits in v4.13.14?
Maybe it is worth opening an Ubuntu-specific CVE, but I'm not sure.
