Overview

Affected versions of this package are vulnerable to Privilege Escalation. The maple tree, responsible for managing virtual memory areas, can undergo node replacement without properly acquiring the MM write lock, leading to use-after-free issues. An unprivileged local user could use this flaw to compromise the kernel and escalate their privileges.
