CVE-2024-27015
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.
Does this matter?
Lower severity and a low EPSS score (0.23%). Track it; it rarely justifies an emergency change on its own.
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.
