Overview

CVE-2026-72301 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:

ASoC: SOF: ipc3-control: Fix TOCTOU in bytes_put and bytes_get

In sof_ipc3_bytes_put(), the size used for the memcpy is derived from

the old data->size already in the buffer, not the incoming new data's

size field. If the new data has a different size, the copy length is

wrong: it may truncate valid data or copy stale bytes.

Similarly, sof_ipc3_bytes_get() checks data->size against max_size

without accounting for the sizeof(struct sof_ipc_ctrl_data) offset

of the flex array within the allocation.

Fix bytes_put to validate and use the incoming data's sof_abi_hdr.size

from ucontrol before copying. Fix bytes_get to subtract sizeof(*cdata)

from the bounds check to match the actual available space.

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-2026-72301?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-72301 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
