Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: most: core: fix leak on early registration failure A recent commit fixed a resource leak on early registration failures but for some reason left out the first error path which still leaks the resources associated with the interface. Fix up also the first error path so that the interface is always released on errors.

Impact Analysis

The vulnerability can lead to resource leaks in the Linux kernel when an interface registration fails early. This could potentially cause increased memory or resource consumption, which might degrade system performance or stability over time.

Executive Summary

This vulnerability is a resource leak in the Linux kernel related to the 'most' core component. Specifically, it involves a failure to properly release resources during early registration failures of an interface.

Although a recent fix addressed some resource leaks on early registration failures, the first error path was overlooked, causing resources associated with the interface to still leak.

The vulnerability was fixed by ensuring that the interface is always released on errors, including the first error path.
