| Subject: CVE-2024-27015: netfilter: flowtable: incorrect pppoe tuple |
| |
| 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. |
| |
| The Linux kernel CVE team has assigned CVE-2024-27015 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
