Overview

CVE-2026-23137 is a medium-severity vulnerability. It was published on February 14, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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:

of: unittest: Fix memory leak in unittest_data_add()

In unittest_data_add(), if of_resolve_phandles() fails, the allocated

unittest_data is not freed, leading to a memory leak.

Fix this by using scope-based cleanup helper __free(kfree) for automatic

resource cleanup. This ensures unittest_data is automatically freed when

it goes out of scope in error paths.

For the success path, use retain_and_null_ptr() to transfer ownership

of the memory to the device tree and prevent double freeing.

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.
