Description
A flaw was found in the Linux kernel's CPSW network driver. When network port registration fails during device initialization, the driver does not properly unregister its devlink management interface. This improper cleanup leaves resources allocated in the kernel, which may allow a local user to cause a resource leak, leading to a Denial of Service (DoS).
