CVE-2026-98556

In the Linux kernel, the following vulnerability has been resolved: gve: DQO: reject TSO packets with an out of range MSS gvepreptso notes that the device requires the MSS to be len and gsosegs, never gsosize. Such a packet reaches gvetxfilltsoctxdesc, which puts gsosize into the mss field of the...

CVE-2026-98556

The Linux kernel contains a vulnerability in the gve driver where TSO (TCP Segmentation Offload) packets with an out-of-range MSS (Maximum Segment Size) are not properly rejected. The gve_prep_tso() function fails to enforce the required limit of

CVE-2026-90063

A flaw was found in virtio-net, a network virtualization driver in the Linux kernel. A local user could exploit this vulnerability by crafting a specially designed TCP packet with a small gsosize value. This action could lead to an integer overflow in the gsosegs field during packet processing,...

AZL-102951 CVE-2026-90063 affecting package kernel for versions less than 6.6.157.1-1

In the Linux kernel, the following vulnerability has been resolved: virtio-net: Ensure that TCP packets don't overflow gsosegs The user can specify any gsosize in a packet crafted with an AFPACKET PACKETVNETHDR socket, even smaller than TCPMINGSOSIZE = 8. At the same time, GSOMAXSIZE = 8 GSOMAXSE...

CVE-2023-54051: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net: do not allow gsosize to be set to GSOBYFRAGS One missing check in virtionethdrtoskb allowed syzbot to crash kernels again 1 Do not allow gsosize to be set to GSOBYFRAGS 0xffff, because this magic value is used by the kernel....

CVE-2022-49872: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net: gso: fix panic on fraglist with mixed head alloc types Since commit 3dcbdb134f32 "net: gso: Fix skbsegment splat when splitting gsosize mangled skb having linear-headed fraglist", it is allowed to change gsosize of a GRO...

CVE-2024-42281

A denial of service vulnerability was found in the Linux kernel. Downgrading gsosize may trigger a crash, resulting in a loss of system availability. Mitigation Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria...

CVE-2024-43817 net: missing check virtio

In the Linux kernel, the following vulnerability has been resolved: net: missing check virtio Two missing check in virtionethdrtoskb allowed syzbot to crash kernels again 1. After the skbsegment function the buffer may become non-linear nrfrags != 0, but since the SKBTXSHAREDFRAG flag is not set...

CVE-2024-42281

CVE-2024-42281 is a Linux kernel vulnerability fixed by the upstream commit: bpf: Fix a segment issue when downgrading gso_size. The fix linearizes the skb when downgrading gso_size to prevent a BUG_ON() later during skb segmentation as described in citations [1,2]. The provided documents confirm...
