Overview

CVE-2026-72302 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: Use overflow checks in control_update size calc

In sof_ipc3_control_update(), the expected_size calculation uses

firmware-provided cdata->num_elems in arithmetic that could overflow

on 32-bit platforms, wrapping to a small value. This would allow the

cdata->rhdr.hdr.size comparison to pass with mismatched sizes,

potentially leading to out-of-bounds access in snd_sof_update_control.

Use check_mul_overflow() and check_add_overflow() to detect and reject

overflowed size calculations.

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.
