CVE-2026-23035 - net/mlx5e: Pass netdev to mlx5e_destroy_netdev instead of priv

CVE ID : CVE-2026-23035 Published : Jan. 31, 2026, 12:16 p.m. | 29 minutes ago Description : In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Pass netdev to mlx5e_destroy_netdev instead of priv mlx5e_priv is an unstable structure that can be memset(0) if profile attaching fails. Pass netdev to mlx5e_destroy_netdev() to guarantee it will work on a valid netdev. On mlx5e_remove: Check validity of priv->profile, before attempting to cleanup any resources that might be not there. This fixes a kernel oops in mlx5e_remove when switchdev mode fails due to change profile failure. $ devlink dev eswitch set pci/0000:00:03.0 mode switchdev Error: mlx5_core: Failed setting eswitch to offloads. dmesg: workqueue: Failed to create a rescuer kthread for wq
