Integrity High (I:H)
Availability High (A:H)

How to Fix CVE-2026-72262

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-72262, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: ipc3-control: Fix heap overflow in bytes_ext put/get The ipc_control_data buffer is allocated as kzalloc(max_size), where max_size covers the entire struct sof_ipc_ctrl_data including its flexible array payload. However, the bounds checks in bytes_ext_put and _bytes_ext_get compared user data lengths against max_size directly, ignoring that cdata->data sits at an offset of sizeof(struct sof_ipc_ctrl_data) bytes into the allocation. This allowed writing up to sizeof(struct sof_ipc_ctrl_data) bytes past the end of the heap buffer from unprivileged userspace via the ALSA TLV kcontrol interface, and similarly allowed over-reading adjacent heap data on the get path. Fix all bounds checks to subtract sizeof(*cdata) from max_size so they reflect the actual space available at the cdata->data offset. Also fix the error-path restore in bytes_ext_put which wrote to cdata->data instead of cdata, causing the same overflow.
