Overview

CVE-2026-31587 is a high-severity vulnerability. It was published on April 24, 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: qcom: q6apm: move component registration to unmanaged version

q6apm component registers dais dynamically from ASoC toplology, which

are allocated using device managed version apis. Allocating both

component and dynamic dais using managed version could lead to incorrect

free ordering, dai will be freed while component still holding references

to it.

Fix this issue by moving component to unmanged version so

that the dai pointers are only freeded after the component is removed.
