Overview

CVE-2026-43460 is a high-severity vulnerability. It was published on May 8, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

spi: rockchip-sfc: Fix double-free in remove() callback

The driver uses devm_spi_register_controller() for registration, which

automatically unregisters the controller via devm cleanup when the

device is removed. The manual call to spi_unregister_controller() in

the remove() callback can lead to a double-free.

And to make sure controller is unregistered before DMA buffer is

unmapped, switch to use spi_register_controller() in probe().

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.
