CVE-2024-36270 is a null-pointer dereference in the Linux kernel netfilter transparent-proxy (TPROXY) IPv4 handling path. The vulnerable code can invoke the IPv4 transparent-proxy local-address logic after IPv4 has been disabled on the selected network device. In this state, the device IPv4 metadata lookup may return NULL, but the result was dereferenced. The fix makes TPROXY stop processing when the required IPv4 device state is unavailable.
