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-2026-72408 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-2026-72408

Summary of the CVE-2026-72408 vulnerability (Linux kernel): The issue, in geneve GRO handling, arises when geneve_gro_complete() processes a GRO hint unconditionally while geneve_gro_receive() may honor the hint only if gs->gro_hint is enabled. This mismatch allowed an attacker-supplied GRO hi...

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...

CVE-2026-72046 gve: fix header buffer corruption with header-split and HW-GRO

In the Linux kernel, the following vulnerability has been resolved: gve: fix header buffer corruption with header-split and HW-GRO The DQO RX datapath programs a per-buffer-queue-descriptor headerbufaddr at post time and reads the split header back at completion time. Both the post and the read...

CVE-2026-72046

The CVE-2026-72046 issue in the Linux kernel concerns the gve RX path, where header buffers were indexed by buffer-queue position (bufq->tail) for posts and by the completion index (desc_idx) for reads. With HW-GRO and multi-flow traffic, out-of-order completions cause headers to be read from ...

CVE-2026-68136

A flaw was found in the Linux kernel's Generic Receive Offload GRO networking subsystem. An attacker could exploit this by sending specially crafted network packets that cause a double aggregation of flush-marked socket buffers skbs. This issue arises from a missing flush check, which allows...

CVE-2026-68136

CVE-2026-68136 is a Linux kernel GRO flaw where missing NAPI_GRO_CB(skb)->flush validation in skb_gro_receive_list() allows double aggregation of flush-marked skbs, potentially corrupting frag_list and leading to a kernel panic during skb_segment() (DoS). Public reports (NVD, Red Hat, Debian, ...
