CVE-2026-43204

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.
