CVE-2026-63861

Published Jul 19, 2026 EPSS 0.17% (7th pctl)

Overview

CVE-2026-63861 is a known-severity vulnerability. It was published on July 19, 2026.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

spi: mtk-snfi: unregister ECC engine on probe failure and remove() callback

mtk_snand_probe() registers the on-host NAND ECC engine, but teardown was

missing from both probe unwind and remove-time cleanup. Add a devm cleanup

action after successful registration so

nand_ecc_unregister_on_host_hw_engine() runs automatically on probe

failures and during device removal.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
