Answer in brief
CVE-2026-72434 records a Unknown severity vulnerability in netfilter: ipset: make sure gc is properly stopped. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: make sure gc is properly stopped Sashiko noticed that when destroying a set, cancel_delayed_work_sync() was called while gc calls queue_delayed_work() unconditionally which can lead not to properly shutting down the gc.
