CVSS: 7.8EPSS: 0%CPEs: 6EXPL: 0CVE-2024-27018 – netfilter: br_netfilter: skip conntrack input hook for promisc packets
https://notcve.org/view.php?id=CVE-2024-27018
In the Linux kernel, the following vulnerability has been resolved: netfilter: br_netfilter: skip conntrack input hook for promisc packets For historical reasons, when bridge device is in promisc mode, packets that are directed to the taps follow bridge input hook path. This patch adds a workaround to reset conntrack for these packets. Jianbo Liu reports warning splats in their test infrastructure where cloned packets reach the br_netfilter input hook to confirm the conntrack object. Scratch one bit from BR_INPUT_SKB_CB to annotate that this packet has reached the input hook because it is passed up to the bridge device to reach the taps.
