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...
