CVE-2026-64510 remediation guide

Linux

In the Linux kernel, the following vulnerability has been resolved: ACPI: NFIT: core: Fix acpi_nfit_init() error cleanup If acpi_nfit_init() fails after adding the acpi_desc object to the acpi_descs list, that object is never removed from that list because the acpi_nfit_shutdown() devm action is not added for the NFIT device in that case. Next, the acpi_nfit_init() failure causes acpi_nfit_probe() to fail, the acpi_desc object is freed, and a dangling pointer is left behind in the acpi_descs. Any subsequent ACPI Machine Check Exception will trigger nfit_handle_mce() which iterates over acpi...

Identify the affected asset

Confirm whether Linux 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: >= a61fe6f7902ecaa89d5e6c709490fc4324927134 < ee82078e776ae31266cc70fdf62ac17c3c6f100a, >= a61fe6f7902ecaa89d5e6c709490fc4324927134 < 6ff054cc02a763914773b026cacb429e5fbf64fa, >= a61fe6f7902ecaa89d5e6c709490fc4324927134 < b07d22a2d17ad6465c87bd5752bc70e4c16e0ee4, >= a61fe6f7902ecaa89d5e6c709490fc4324927134 < c127dbd832bd4b9aef8a749d9f491b74042f9b47, >= a61fe6f7902ecaa89d5e6c709490fc4324927134 < df7c92216a1583a76cb0cbf2f21cd68870609b05, >= a61fe6f7902ecaa89d5e6c709490fc4324927134 < 3b2628f7682aea8d9ce09ad4b9a3bd144b451eaa, >= a61fe6f7902ecaa89d5e6c709490fc4324927134 < 7d69235bdc581a4346e9bcd6a8bea37d3e1abd25, >= a61fe6f7902ecaa89d5e6c709490fc4324927134 < 38bf27511ef41bffebd157ec3eba41fc89ba59cd, >= 4.6. 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.
