CVE-2026-97982

The Linux kernel contains a vulnerability in the net: ethernet: cortina driver. Specifically, the gmac_rx() function incorrectly returns the remaining NAPI budget instead of the number of packets received. This causes an idle poll to report a full budget and remain scheduled. The fix involves upd...

EUVD-2026-86636

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: cortina: Fix budget accounting The gmacrx function returns the remaining NAPI budget, but its caller treats the return value as the number of packets received. An idle poll therefore reports a full budget and remai...

CVE-2026-97981

The Linux kernel contains a vulnerability in the net: ethernet: cortina driver where the RX loop only consumed the NAPI budget upon successful frame delivery. Consequently, error paths continued to consume descriptors without reducing the budget, allowing a stream of bad frames to process the ent...

Astra Linux – Vulnerability in Linux 6.1

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 Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-099770 advisory. In the Linux kernel, the following vulnerability has been resolved: net: ethernet: cortina: Carry over frag counter The gmacrx NAPI poll function assembles packets i...

Unity Linux 20.1050a Security Update: kernel (UTSA-2026-100586)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-100586 advisory. 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...

SUSE CVE-2026-64055

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: cortina: Carry over frag counter The gmacrx NAPI poll function assembles packets in an SKB from a ring buffer. If the ring buffer gets completely emptied during a poll cycle, we exit gmacrx, but the packet is not y...

SUSE CVE-2026-64056

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 ...

CVE-2026-64055

A flaw was found in the Linux kernel's Cortina ethernet driver. When the network interface processes incoming packets, a counter used for reassembling fragmented packets can be prematurely reset. This can lead to incomplete packet reassembly, potentially causing network communication issues or...

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

The CVE covers a Linux kernel issue in the Cortina ethernet driver. The RX socket buffer (SKB) used to assemble fragments in gmac_rx() was a static local variable, which could race on devices with two ethernet ports (Gemini) when both ports are active. The fix makes the RX SKB a per-port variable...
