Overview

CVE-2026-23068 is a high-severity vulnerability. It was published on February 4, 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: spi-sprd-adi: Fix double free in probe error path

The driver currently uses spi_alloc_host() to allocate the controller

but registers it using devm_spi_register_controller().

If devm_register_restart_handler() fails, the code jumps to the

put_ctlr label and calls spi_controller_put(). However, since the

controller was registered via a devm function, the device core will

automatically call spi_controller_put() again when the probe fails.

This results in a double-free of the spi_controller structure.

Fix this by switching to devm_spi_alloc_host() and removing the

manual spi_controller_put() call.

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.
