What is CVE-2026-1679?

The eswifi socket offload driver presents a security vulnerability due to its mishandling of user-provided payloads. When payloads are copied into a fixed buffer, the driver does not adequately verify the available space, leading to potential buffer overflow issues that can corrupt kernel memory. This vulnerability requires local code execution that can invoke the socket send API, thus limiting remote exploit possibilities.
