IBM Storage Scale System

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within the Linux kernel netfilter: nf_tables component. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
