The napi_reuse_skb function in net/core/dev.c in the Generic Receive Offload (GRO) implementation in the Linux kernel before 2.6.38 does not reset the values of certain structure members, which might allow remote attackers to cause a denial of service (NULL pointer dereference) via a malformed VLAN frame.

Security readout for executives and security teams

CVE-2011-1478 is an old Linux kernel denial-of-service flaw. A malformed VLAN network frame could crash affected systems by triggering a NULL pointer dereference in GRO packet handling. It matters mainly for legacy systems running kernels before 2.6.38 or vendor products that embedded those kernels. Exposure is most plausible on legacy Linux systems, appliances, or virtualization platforms using Linux kernel code before 2.6.38. The bundle does not provide complete affected vendor/version mapping, so exposure should be verified through kernel version and vendor backport records. Prioritize this for legacy-risk cleanup rather than emergency response. If no pre-2.6.38 or vendor-affected systems remain, business urgency is low. If legacy network-facing infrastructure exists, schedule remediation because impact is service outage. Mitigation focus: Upgrade affected Linux kernels to 2.6.38 or a vendor-fixed supported kernel.; Check vendor advisories for backported fixes on maintained enterprise kernels.; Prioritize exposed network infrastructure, virtualization hosts, and legacy appliances..
