CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of Ethernet packets, specifically in the Gemini architecture where a static local SKB (socket buffer) can lead to race conditions when both Ethernet ports are in use. This flaw could allow an attacker to exploit the race conditions, potentially leading to data corruption or denial of service. Organizations utilizing Linux systems with Gemini Ethernet ports should prioritize patching this critical vulnerability to mitigate risks associated with network instability and security breaches.
Original NVD Description
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 gmac_rx() 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 is using both. Make the RX SKB a per-port variable and carry it over between invocations in the port struct instead. Zero the pointer once we call napi_gro_frags(), on error (after calling napi_free_frags()) or if the port is stopped. Zero it in some place where not strictly necessary just to emphasize what is going on. This was found by Sashiko during normal patch review.
