Overview

CVE-2026-53297 is a medium-severity vulnerability. It was published on June 26, 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:

net: mana: Guard mana_remove against double invocation

If PM resume fails (e.g., mana_attach() returns an error), mana_probe()

calls mana_remove(), which tears down the device and sets

gd->gdma_context = NULL and gd->driver_data = NULL.

However, a failed resume callback does not automatically unbind the

driver. When the device is eventually unbound, mana_remove() is invoked

a second time. Without a NULL check, it dereferences gc->dev with

gc == NULL, causing a kernel panic.

Add an early return if gdma_context or driver_data is NULL so the second

invocation is harmless. Move the dev = gc->dev assignment after the

guard so it cannot dereference NULL.

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.
