What to do

AI-suggested

A fix for this vulnerability has been implemented by changing the component registration to an unmanaged version, ensuring that DAIs are freed only after the component is removed. Users should apply the official Linux kernel updates that include this fix once available.

Description

CVE-2026-31587 is a use-after-free vulnerability in the Linux kernel's ASoC qcom q6apm component. The issue arises because the component and its dynamic DAIs (Digital Audio Interfaces) are allocated using device-managed APIs, leading to incorrect free ordering. This can cause the DAIs to be freed while the component still holds references to them, resulting in a kernel memory corruption. The vulnerability has a high severity score of 7.8 and affects the Linux kernel's sound subsystem.
