CVE-2026-72408 geneve: gate GRO hint in geneve_gro_complete() on gs->gro_hint

In the Linux kernel, the following vulnerability has been resolved: geneve: gate GRO hint in genevegrocomplete on gs-grohint genevegroreceive reads the GRO hint through geneveskgrohintoff, which honours it only when the socket enabled IFLAGENEVEGROHINT gs-grohint. genevegrocomplete instead calls...

CVE-2026-72407 geneve: validate inner network offset in geneve_gro_complete()

In the Linux kernel, the following vulnerability has been resolved: geneve: validate inner network offset in genevegrocomplete Even with both paths gated on gs-grohint, genevegrocomplete re-derives the inner dispatch type and length from the packet and the current gs-grohint, independently of...

CVE-2026-72407

The CVE describes a Linux kernel vulnerability in geneve GRO handling where geneve_gro_complete() could derive a dispatch offset from stale or conflicting state (gs->gro_hint) vs the actual inner header parsed by geneve_gro_receive(), potentially leading to out-of-bounds processing. The fix en...

In the Linux kernel, the following vulnerability has been resolved: vmxnet3: fix BUGON in vmxnet3gethdrlen for Geneve packets vmxnet3gethdrlen assumes gdesc-rcd.v4/v6/tcp always describe the outer header, but for a Geneve-encapsulated packet the device can set them based on the inner header...

CVE-2026-68142

A flaw was found in the geneve component of the Linux kernel. A local attacker, with CAPNETADMIN privileges in a specific network namespace, could bypass intended permission checks. This allows them to modify the configuration of a geneve network device in a different network namespace, potential...

CVE-2026-68299

A flaw was found in the vmxnet3 virtual network device driver within the Linux kernel. When processing Geneve-encapsulated packets, the vmxnet3gethdrlen function can incorrectly interpret header information, leading to a mismatch between expected and actual packet protocols or IP versions. This c...
