CVE-2025-40252 remediation guide

Linux Linux, RUGGEDCOM RST2428P

In the Linux kernel, the following vulnerability has been resolved: net: qlogic/qede: fix potential out-of-bounds read in qede_tpa_cont() and qede_tpa_end() The loops in 'qede_tpa_cont()' and 'qede_tpa_end()', iterate over 'cqe->len_list[]' using only a zero-length terminator as the stopping condition. If the terminator was missing or malformed, the loop could run past the end of the fixed-size array. Add an explicit bound check using ARRAY_SIZE() in both loops to prevent a potential out-of-bounds access. Found by Linux Verification Center (linuxtesting.org) with SVACE.

Identify the affected asset

Confirm whether Linux Linux, RUGGEDCOM RST2428P 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: >= 55482edc25f0606851de42e73618f813f310d009 < ecbb12caf399d7cf364b7553ed5aebeaa2f255bc, >= 55482edc25f0606851de42e73618f813f310d009 < a778912b4a53587ea07d85526d152f85d109cbfe, >= 55482edc25f0606851de42e73618f813f310d009 < f0923011c1261b33a2ac1de349256d39cb750dd0, >= 55482edc25f0606851de42e73618f813f310d009 < 917a9d02182ac8b4f25eb47dc02f3ec679608c24, >= 55482edc25f0606851de42e73618f813f310d009 < e441db07f208184e0466abf44b389a81d70c340e, >= 55482edc25f0606851de42e73618f813f310d009 < 896f1a2493b59beb2b5ccdf990503dbb16cb2256, >= 4.6, < V4.0. 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: No verified fixed-version field is available yet. 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.
