CVE-2026-43204 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: qcom: q6asm: drop DSP responses for closed data streams 'Commit a354f030dbce ("ASoC: qcom: q6asm: handle the responses after closing")' attempted to ignore DSP responses arriving after a stream had been closed. However, those responses were still handled, causing lockups. Fix this by unconditionally dropping all DSP responses associated with closed data streams.
A vulnerability in the Linux kernel's Audio Stream Control (ASoC) component for Qualcomm Digital Signal Processor (DSP) responses has been addressed. The issue arose because responses from the DSP were still processed after a data stream had been closed, leading to system lockups. The vulnerability affected several versions of the Linux kernel. The root cause was improper handling of DSP responses, which should have been dropped unconditionally for closed streams. The vulnerability could cause lockups by allowing closed stream responses to interfere with the normal operation of the audio processing system.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version are available on the Linux kernel official website.
