CVE-2026-43060
7.8
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nft_ct: drop pending enqueued packets on removal
Packets sitting in nfqueue might hold a reference to:
- templates that specify the conntrack zone, because a percpu area is used and module removal is possible.
- conntrack timeout policies and helper, where object removal leave a stale reference.
Since these objects can just go away, drop enqueued packets to avoid stale reference to them.
If there is a need for finer grain removal, this logic can be revisited to make selective packet drop upon dependencies.
