Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Linux/Linux, Linux/Linux, Linux/Linux.
  2. 2Review the reported fix. Update Linux/Linux to 8947215c0136c9d905e4a46d824824f8b48a2e5b; Linux/Linux to 3e339c88b8c3044919fd1936a8b23124285d0de6; Linux/Linux to b3647e5b7b817272fdef057948c37fcb0704edc7 if you use the affected versions. Test the change in a non-production environment first.

Upstream source description

In the Linux kernel, the following vulnerability has been resolved: ALSA: hda/cs35l41: Fix firmware load work teardown cs35l41_hda creates ALSA controls whose private data points at the cs35l41_hda object. The firmware load control can also queue fw_load_work. Those controls are not removed on component unbind, and device remove only cancels fw_load_work through cs35l41_remove_dsp(). That helper is skipped when halo_initialized is false. With firmware_autostart disabled, a firmware load can be requested before the DSP has been initialized. If the component or device is removed before the queued work runs, the worker can run after teardown and dereference driver state that is no longer valid. Track the created controls and remove them on unbind so no new control callback can reach the driver data or queue more work. Then cancel fw_load_work to drain any request that was already queued. Also cancel the work unconditionally during device remove before runtime PM teardown.
