CVE-2024-27018

CVE-2024-27018 affects the Linux kernel br_netfilter component. The issue arises when a bridge device is in promiscuous mode, causing certain bridge-tapped packets to bypass conntrack input handling; a patch resets the conntrack state for these packets. The crash/reply trace and warnings (br_nf_l...
