CVE-2024-27015 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.23% chance of exploitation in the next 30 days.
