CVE-2024-26951 remediation guide

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

In the Linux kernel, the following vulnerability has been resolved: wireguard: netlink: check for dangling peer via is_dead instead of empty list If all peers are removed via wg_peer_remove_all(), rather than setting peer_list to empty, the peer is added to a temporary list with a head on the stack of wg_peer_remove_all(). If a netlink dump is resumed and the cursored peer is one that has been removed via wg_peer_remove_all(), it will iterate from that peer and then attempt to dump freed peers. Fix this by instead checking peer->is_dead, which was explictly created for this purpose. Also mo...

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: >= e7096c131e5161fa3b8e52a650d7719d2857adfd < f52be46e3e6ecefc2539119784324f0cbc09620a, >= e7096c131e5161fa3b8e52a650d7719d2857adfd < 710a177f347282eea162aec8712beb1f42d5ad87, >= e7096c131e5161fa3b8e52a650d7719d2857adfd < b7cea3a9af0853fdbb1b16633a458f991dde6aac, >= e7096c131e5161fa3b8e52a650d7719d2857adfd < 13d107794304306164481d31ce33f8fdb25a9c04, >= e7096c131e5161fa3b8e52a650d7719d2857adfd < 7bedfe4cfa38771840a355970e4437cd52d4046b, >= e7096c131e5161fa3b8e52a650d7719d2857adfd < 302b2dfc013baca3dea7ceda383930d9297d231d, >= e7096c131e5161fa3b8e52a650d7719d2857adfd < 55b6c738673871c9b0edae05d0c97995c1ff08c4, >= 5.6, >= 5.6 < 5.10.215, >= 5.11 < 5.15.154, >= 5.16 < 6.1.84, >= 6.2 < 6.6.24, >= 6.7 < 6.7.12, >= 6.8 < 6.8.3, 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: 5.10.215, 5.15.154, 6.1.84, 6.6.24, 6.7.12, 6.8.3. 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.
