Description

In the Linux kernel, the following vulnerability has been resolved: netfilter: flowtable: incorrect pppoe tuple pppoe traffic reaching ingress path does not match the flowtable entry because the pppoe header is expected to be at the network header offset. This bug causes a mismatch in the flow table lookup, so pppoe packets enter the classical forwarding path.
