CVE-2024-35898 remediation guide

Linux Linux, SIMATIC S7-1500 TM MFP - GNU/Linux subsystem, linux kernel

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: Fix potential data-race in __nft_flowtable_type_get() nft_unregister_flowtable_type() within nf_flow_inet_module_exit() can concurrent with __nft_flowtable_type_get() within nf_tables_newflowtable(). And thhere is not any protection when iterate over nf_tables_flowtables list in __nft_flowtable_type_get(). Therefore, there is pertential data-race of nf_tables_flowtables list entry. Use list_for_each_entry_rcu() to iterate over nf_tables_flowtables list in __nft_flowtable_type_get(), and use rcu_read_lo...

Identify the affected asset

Confirm whether Linux Linux, SIMATIC S7-1500 TM MFP - GNU/Linux subsystem, linux kernel is installed, record the deployed version and installation path, and identify exposed interfaces.

Record the product name, package or appliance identifier, and installed version.
Identify internet-facing, administrative, API, and internal access paths.
Preserve the pre-change configuration and relevant service logs.

Validate the affected-version match

Compare the deployed version with the affected range: >= 3b49e2e94e6ebb8b23d0955d9e898254455734f8 < 69d1fe14a680042ec913f22196b58e2c8ff1b007, >= 3b49e2e94e6ebb8b23d0955d9e898254455734f8 < a347bc8e6251eaee4b619da28020641eb5b0dd77, >= 3b49e2e94e6ebb8b23d0955d9e898254455734f8 < 940d41caa71f0d3a52df2fde5fada524a993e331, >= 3b49e2e94e6ebb8b23d0955d9e898254455734f8 < 2485bcfe05ee3cf9ca8923a94fa2e456924c79c8, >= 3b49e2e94e6ebb8b23d0955d9e898254455734f8 < 9b5b7708ec2be21dd7ef8ca0e3abe4ae9f3b083b, >= 3b49e2e94e6ebb8b23d0955d9e898254455734f8 < 8b891153b2e4dc0ca9d9dab8f619d49c740813df, >= 3b49e2e94e6ebb8b23d0955d9e898254455734f8 < e684b1674fd1ca4361812a491242ae871d6b2859, >= 3b49e2e94e6ebb8b23d0955d9e898254455734f8 < 24225011d81b471acc0e1e315b7d9905459a6304, >= 4.16, >= 4.16 < 4.19.312, >= 4.20 < 5.4.274, >= 5.5 < 5.10.215, >= 5.11 < 5.15.154, >= 5.16 < 6.1.85, >= 6.2 < 6.6.26, >= 6.7 < 6.8.5, 6.9, 10.0. Treat incomplete inventory results as unresolved.

Prioritize with independent signals

The CVSS severity warrants an early asset and exposure review. Combine this signal with asset criticality, exposure, compensating controls, and business impact.

Apply supported remediation

Follow the vendor advisory or supported update path. Current fixed-version status: 4.19.312, 5.4.274, 5.10.215, 5.15.154, 6.1.85, 6.6.26, 6.8.5. Preserve configuration and rollback material before change.

Verify the result

Confirm the resulting version, service health, authentication and access paths, monitoring coverage, and relevant security logs.

Confirm the expected version and package state.
Run a functional health check for critical service paths.
Review authentication, error, application, and security monitoring logs.
Reassess exposure if the supported fix cannot be applied.

Operational boundary

This page does not replace the vendor advisory, support contract, change-management process, or recovery plan. Do not infer that an asset is unaffected from an incomplete inventory query or a missing fixed-version field.
