CVE-2026-68299 vmxnet3: fix BUG_ON in vmxnet3_get_hdr_len() for Geneve packets

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-2026-68299

Summary: CVE-2026-68299 affects the Linux kernel vmxnet3 driver. When handling Geneve-encapsulated packets, vmxnet3_get_hdr_len() may misinterpret header fields because gdesc->rcd.v4/v6/tcp describe the outer header, while the inner header can differ. The completion descriptor’s VMXNET3_RCD_HD...

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...

kernel: netfilter: nft_inner: Fix IPv6 inner_thoff desync

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nftinner module. This vulnerability arises from an incorrect handling of IPv6 inner packet processing, where the transport header offset innerthoff becomes desynchronized from the Layer 4 protocol l4proto. A remot...

CVE-2026-53228

The CVE-2026-53228 entry documents a vulnerability in the Linux kernel SIT IPv6 tunnel driver. When GSO offloads are used, the code may keep a stale pointer to the inner IPv6 header after skb header unclone and potential headroom reallocation, leading to reads from freed memory. A fix reloads the...
