CVE-2026-31431 remediation guide

Linux Linux, NVIDIA for RHEL 10, Red Hat Enterprise Linux 10

In the Linux kernel, the following vulnerability has been resolved: crypto: algif_aead - Revert to operating out-of-place This mostly reverts commit 72548b093ee3 except for the copying of the associated data. There is no benefit in operating in-place in algif_aead since the source and destination come from different mappings. Get rid of all the complexity added for in-place operation and just copy the AD directly.

Identify the affected asset

Confirm whether Linux Linux, NVIDIA for RHEL 10, Red Hat Enterprise Linux 10 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: >= 72548b093ee38a6d4f2a19e6ef1948ae05c181f7 < 893d22e0135fa394db81df88697fba6032747667, >= 72548b093ee38a6d4f2a19e6ef1948ae05c181f7 < 19d43105a97be0810edbda875f2cd03f30dc130c, >= 72548b093ee38a6d4f2a19e6ef1948ae05c181f7 < 961cfa271a918ad4ae452420e7c303149002875b, >= 72548b093ee38a6d4f2a19e6ef1948ae05c181f7 < 3115af9644c342b356f3f07a4dd1c8905cd9a6fc, >= 72548b093ee38a6d4f2a19e6ef1948ae05c181f7 < 8b88d99341f139e23bdeb1027a2a3ae10d341d82, >= 72548b093ee38a6d4f2a19e6ef1948ae05c181f7 < fafe0fa2995a0f7073c1c358d7d3145bcc9aedd8, >= 72548b093ee38a6d4f2a19e6ef1948ae05c181f7 < ce42ee423e58dffa5ec03524054c9d8bfd4f6237, >= 72548b093ee38a6d4f2a19e6ef1948ae05c181f7 < a664bf3d603dc3bdcf9ae47cc21e0daec706d7a5, >= 4.14, >= V3.1.6, >= V3.1.5, >= 4.14 < 5.10.254, >= 5.11 < 5.15.204, >= 5.16 < 6.1.170, >= 6.2 < 6.6.137, >= 6.7 < 6.12.85, >= 6.13 < 6.18.22, >= 6.19 < 6.19.12, 7.0, >= 4.12 < 4.12.89. Treat incomplete inventory results as unresolved.

Prioritize with independent signals

CISA has listed this vulnerability in the Known Exploited Vulnerabilities catalog. Combine this signal with asset criticality, exposure, compensating controls, and business impact.

Apply supported remediation

"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

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.
