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.

CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
