AI-suggested

A patch is available and included in Linux kernel versions 5.4.0-1077.82~18.04.1 and later, as well as 5.15.0-1069.75~20.04.1 and others. Users should apply the official kernel updates provided by their Linux distribution vendors, such as the Ubuntu security notice USN-6951-1. After updating, a system reboot is required. Due to ABI changes, recompilation and reinstallation of third-party kernel modules may be necessary.

Description

CVE-2024-38659 is a vulnerability in the Linux kernel's enic driver where the function enic_set_vf_port improperly assumes certain netlink attributes have fixed lengths. This can lead to out-of-bounds read access during memory copy operations. The issue arises because the length validation uses a policy that only enforces maximum sizes, not exact sizes, causing potential memory safety violations. Multiple Linux kernel versions prior to fixed releases are affected. A patch correcting this flaw is available and included in various Linux kernel updates.
