Background
The net/mlx5 package is a component of the Linux Kernel ecosystem. It provides support for Mellanox network adapters, specifically the mlx5 driver. The mlx5_cmd_dr_create_fte function is responsible for creating a flow table entry (FTE) in the Mellanox ConnectX-4 and ConnectX-5 network adapters. This vulnerability affects versions of the Linux Kernel from v5.16 to v5.16.11, and it was introduced in v5.16. The vulnerability allows an attacker to trigger a slab-out-of-bounds condition in the mlx5_cmd_dr_create_fte function, potentially leading to a denial-of-service (DoS) or arbitrary code execution.
Vulnerability Detail
The vulnerability in net/mlx5's mlx5_cmd_dr_create_fte function arises from a slab-out-of-bounds condition. This occurs when the function attempts to access memory outside the bounds of an allocated slab. An attacker can exploit this vulnerability by crafting a malicious input that triggers the out-of-bounds access. The impact of this vulnerability includes potential denial-of-service (DoS) attacks or arbitrary code execution. The vulnerability was fixed in Linux Kernel version v5.16.12 by commit 4ad319cdfbe555b4ff67bc608736c46a6930c848.
