The udp6_ufo_fragment function in net/ipv6/udp.c in the Linux kernel before 2.6.39, when a certain UDP Fragmentation Offload (UFO) configuration is enabled, allows remote attackers to cause a denial of service (system crash) by sending fragmented IPv6 UDP packets to a bridge device.

Security readout for executives and security teams

CVE-2011-4326 is a Linux kernel crash issue in a specific IPv6 UDP offload path. A remote attacker could trigger denial of service against systems using the affected kernel behavior with bridge devices. The sources do not show data theft or code execution. Likely exposure is older Linux systems or vendor kernels derived from pre-2.6.39 code, especially hosts using IPv6, UDP offload behavior, and bridge devices. Modern supported kernels are less likely affected, but vendor backport status must be verified. Address during legacy Linux risk reduction or network infrastructure hardening. Escalate if internet-facing or multi-tenant bridge hosts run affected kernels. Business impact is availability loss, not confirmed compromise. Mitigation focus: Upgrade to a vendor-supported kernel containing the upstream fix.; Verify vendor advisories for backported fixes in enterprise kernels.; Prioritize systems exposing IPv6 bridge traffic or virtualization bridge roles..
