CVE-2026-64056

A flaw was found in the Linux kernel's Cortina ethernet driver for Gemini devices. The driver used a single, shared buffer SKB, or Socket Kernel Buffer for assembling incoming network packets across multiple ethernet ports. This shared resource could lead to race conditions, where simultaneous...

CVE-2026-64056 net: ethernet: cortina: Make RX SKB per-port

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: cortina: Make RX SKB per-port The SKB used to assemble packets from fragments in gmacrx is static local, but the Gemini has two ethernet ports, meaning there can be races between the ports on a bad day if a device ...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: Net: Ethernet: Cortina: Use TOE/TSO for all TCP protocols. It is desirable to enable the hardware accelerator to also process non-segmented TCP frames. We can pass the skb-len value to the “TOE/TSO” offloader, which will handle...

The issue causes instability, lockups, and...

CVE-2025-38331: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: cortina: Use TOE/TSO on all TCP It is desireable to push the hardware accelerator to also process non-segmented TCP frames: we pass the skb-len to the "TOE/TSO" offloader and it will handle them. Without this quirk...
