How to fix?

Upgrade Debian:unstable iproute2 to version 5.2.0-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream iproute2 package and not the iproute2 package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

iproute2 before 5.1.0 has a use-after-free in get_netnsid_from_name in ip/ipnetns.c. NOTE: security relevance may be limited to certain uses of setuid that, although not a default, are sometimes a configuration option offered to end users. Even when setuid is used, other factors (such as C library configuration) may block exploitability.
