Linux Kernel Vulnerability Affecting Networking Team Device Management

CVE-2025-39733

What is CVE-2025-39733?

A vulnerability exists in the Linux kernel related to the management of team devices, which previously relied on team locks. Due to reported ordering issues when using lower instance locks, a transition to the rtnl locking mechanism has been implemented to enhance protection for team devices, aligning its functionality with that of bonding devices. This change aims to ensure consistent and reliable access control for these devices, minimizing potential security threats.
