CVE-2026-72056

Published Aug 15, 2026 EPSS 0.22% (12th pctl)

Overview

CVE-2026-72056 is a known-severity vulnerability. It was published on August 15, 2026.

Technical Description

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

net: ena: clean up XDP TX queues when regular TX setup fails

create_queues_with_size_backoff() creates XDP TX queues before setting

up the regular TX path. If the subsequent allocation or creation of

regular TX queues fails, the error handling paths omit the teardown of the

XDP TX queues, leading to a resource leak.

Fix this by explicitly destroying the XDP TX queue subset at the two

missing failure points.

The bug was first flagged by an experimental analysis tool we are

developing for kernel memory-management bugs while analyzing

v6.13-rc1. The tool is still under development and is not yet publicly

available. Manual inspection confirms that the bug is still

present in v7.1-rc7.

An x86_64 allyesconfig build showed no new warnings. As we do not have

an ENA device to test with, no runtime testing was able to be performed.

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.
