CVE-2024-35897: netfilter: nf_tables: discard table flag update with pending basechain deletion

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: discard table flag update with pending basechain deletion Hook unregistration is deferred to the commit phase, same occurs with hook updates triggered by the table dormant flag. When both commands are combined, this results in deleting a basechain while leaving its hook still registered in the core.

Security readout for executives and security teams

Plain-English summary

CVE-2024-35897 is a Linux kernel netfilter nf_tables flaw. A specific table flag change combined with deleting a basechain can leave a network hook registered after the chain is deleted. The public record confirms kernel fixes, but does not provide CVSS, CWE, or direct business impact details.

Executive priority

Handle through normal kernel patch governance unless vendor advisories raise local impact. There is no cited active exploitation, but kernel networking flaws can affect high-value infrastructure and embedded products, so asset coverage matters more than perimeter exposure alone.

Technical view

The issue is in nf_tables transaction handling. Hook unregistration is deferred until commit, as are hook updates from the table dormant flag. Combining those operations can delete a basechain while its hook remains registered in the core. Stable kernel commits address this by discarding the conflicting table flag update.

Likely exposure

Exposure is most likely on Linux systems running affected kernel versions with nf_tables/netfilter available. Internet-facing status alone is not enough; validation should focus on kernel versions, distribution backports, and whether appliances or embedded products include affected Linux kernels.

Exploitation context

The provided sources do not show active exploitation, and CISA KEV status is false. The bundle also does not include public exploit evidence. Treat this as a kernel-level flaw requiring patch tracking, especially where untrusted users or workloads can influence local networking configuration.

Researcher notes

The record is sparse: no CVSS, CWE, exploit status, or detailed impact category is provided. Analysis should stay tied to the nf_tables transaction condition and stable Linux fixes. Distribution kernels may be fixed by backport without matching upstream version numbers.

Mitigation direction

  • Update to a vendor kernel containing the referenced stable fixes.
  • Check Debian LTS and appliance vendor advisories for backported fixes.
  • Prioritize shared hosts, containers, and systems permitting local network administration.
  • If patch timing is unclear, follow vendor hardening guidance for nf_tables exposure.

Validation and detection

  • Inventory Linux kernel versions across servers, appliances, and images.
  • Map installed kernels to vendor advisories or stable commit backports.
  • Confirm whether nf_tables is enabled or required on exposed systems.
  • Review change records for kernel updates after the 2024-05-19 publication date.
