The firmware loader keeps the\ncallback module pinned and holds a device reference, but the callback\nstill uses driver-private HDA state.\n\nComponent unbind removes controls and DSP state immediately. Later\ndevice removal tears down the TAS2781 private data, including\ncodec_lock. If the async firmware callback runs after unbind has\nstarted, it can operate on state that is being torn down.\n\nCancel or synchronize the async firmware request before removing\ncontrols and DSP state. A queued callback is cancelled, and an\nalready-running callback is allowed to finish before unbind continues.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/5367e2ad14f0ae9350a7aaf2e77c87de39a43ae9","https://git.kernel.org/stable/c/da9e3be9cf31d7138d23e9e2f7ba1c102ef09f07","https://git.kernel.org/stable/c/f8272331da877eec8fe8e89a1e98e6a710e12490"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-80872","score":0.00206,"percentile":0.10738,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
