Double free vulnerability in the xfrm6_tunnel_rcv function in net/ipv6/xfrm6_tunnel.c in the Linux kernel before 2.6.22, when the xfrm6_tunnel module is enabled, allows remote attackers to cause a denial of service (panic) via crafted IPv6 packets.

Security readout for executives and security teams

This is an old Linux kernel denial-of-service flaw. Systems running kernels before 2.6.22 with the xfrm6_tunnel module enabled could panic after receiving crafted IPv6 packets. The sources describe service disruption, not data theft or code execution. Exposure is most plausible on legacy Linux systems, embedded appliances, or vendor-maintained platforms still using affected pre-2.6.22 kernel code with IPv6 xfrm tunneling enabled. Treat as a legacy infrastructure risk. Prioritize internet-facing or untrusted-network systems first, especially appliances or unsupported Linux builds where kernel patch status is unclear. Mitigation focus: Upgrade affected systems to a vendor kernel containing the referenced upstream fix.; Check Red Hat, HP, or relevant vendor advisories for supported package guidance.; Inventory legacy Linux and appliance kernels that may include pre-2.6.22 code..
