Overview

CVE-2026-23026 is a medium-severity vulnerability. It was published on January 31, 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:

dmaengine: qcom: gpi: Fix memory leak in gpi_peripheral_config()

Fix a memory leak in gpi_peripheral_config() where the original memory

pointed to by gchan->config could be lost if krealloc() fails.

The issue occurs when:

1. gchan->config points to previously allocated memory

2. krealloc() fails and returns NULL

3. The function directly assigns NULL to gchan->config, losing the

reference to the original memory

4. The original memory becomes unreachable and cannot be freed

Fix this by using a temporary variable to hold the krealloc() result

and only updating gchan->config when the allocation succeeds.

Found via static analysis and code review.

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.

How can CyberStrike help with CVE-2026-23026?

CyberStrike is an open-source, AI-augmented pentesting engine.
