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state that is no longer valid.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. (NVD)
