CVE-2026-72245

Technical Description

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

gpu: host1x: Fix device reference leak in host1x_device_parse_dt() error path

After device_initialize(), the embedded struct device in struct

host1x_device should be released through the device core with

put_device().

In host1x_device_add(), if host1x_device_parse_dt() fails, the current

error path frees the object directly with kfree(device). That bypasses

the normal device lifetime handling and leaks the reference held on the

embedded struct device.

The issue was identified by a static analysis tool I developed and

confirmed by manual review.

Fix this by using put_device() in the host1x_device_parse_dt() failure

path.

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.
