EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 93% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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device is removed before the queued work runs, the worker can run after teardown and dereference driver state that is no longer valid.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.
