The NAT code (1) ip_nat_proto_tcp.c and (2) ip_nat_proto_udp.c in Linux kernel 2.6 before 2.6.13 and 2.4 before 2.4.32-rc1 incorrectly declares a variable to be static, which allows remote attackers to cause a denial of service (memory corruption) by causing two packets for the same protocol to be NATed at the same time, which leads to memory corruption.

Security readout for executives and security teams

CVE-2005-3275 is an old Linux kernel NAT flaw. A vulnerable gateway or firewall doing NAT could crash or suffer memory corruption when concurrent packets for the same protocol are processed. The main business risk is outage of legacy network infrastructure, not confirmed data theft. Exposure is most likely on obsolete Linux 2.4 or early 2.6 systems that perform NAT, such as legacy routers, firewalls, appliances, or embedded gateways. Supported modern Linux distributions are unlikely to be affected if vendor kernel updates were applied. Treat this as a legacy infrastructure risk. It deserves prompt attention only if old Linux NAT devices remain in production; otherwise it is mainly an inventory and assurance item. Mitigation focus: Inventory Linux NAT gateways and embedded appliances for affected kernel versions.; Apply vendor kernel updates from the relevant distribution advisory.; Upgrade beyond Linux 2.6.13 or 2.4.32-rc1 where vendor guidance supports it..
