A flaw was found in the Linux kernel’s implementation of some networking
protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an
encrypted tunnel is created between two hosts, the kernel isn’t correctly
routing tunneled data over the encrypted link; rather sending the data
unencrypted. This would allow anyone in between the two endpoints to read
the traffic unencrypted. The main threat from this vulnerability is to data
confidentiality.
