CVE-2026-98792

/// Technical description

In the Linux kernel, the following vulnerability has been resolved:

netfilter: flowtable: generalize pending status bit

Rename NF_FLOW_HW_PENDING to NF_FLOW_PENDING and use it to inhibit the

flowtable GC worker until pending hw offload work has been completed.

Apparently, nf_flow_offload_stats() can schedule work to retrieve stats

while the flow is being removed by GC.

And this bit can also be used in a follow up patch to disable GC until

the flow has been fully added in both directions.

Revert the reordering done in commit d644b23afe1e ("netfilter:

flowtable: publish HW_DEAD after worker is done") to prevent a race

between GC and hw offload handler.

/// Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
