Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)

Description: The issue arises when copying a namespace in the Linux kernel. Specifically, the new copy is not added to the namespace rbtree until after the copy operation has succeeded. However, when free mnt ns() is called, it attempts to remove the copy from the rbtree, which is an invalid operation. To resolve this, the namespace skeleton is freed directly.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
