Memory Leak in Ice Networking Driver for Linux Kernel

CVE-2025-38417

What is CVE-2025-38417?

A memory leak exists in the Ice networking driver within the Linux kernel, caused by improper handling of port representor memory structures during the reset procedures in switchdev mode. When a virtual function (VF) is involved, the system may attach or detach the VF incorrectly, leading to excessive memory allocation without proper deallocation, particularly in legacy configurations. This oversight can affect system performance and resource management, making it essential for users to apply relevant updates.
