There is also the\nvery real potential for this code to remove ALL debugfs entries from the\nsystem, and it seems like this is what will really happen if this code\never runs.  This all is very wrong as the greybus audio driver did not\ncreate this debugfs file, the sound core did and controls the lifespan\nof it.\n\nSo remove all of the debugfs logic from the audio_helper code as there's\nno way it could be correct.  If this really is needed, it can come back\nwith a fixup for the incorrect usage of the debugfs_lookup() call which\nis what caused this to be noticed at all.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-401"],"references":["https://git.kernel.org/stable/c/4dab0d27a4211a27135a6899d6c737e6e0759a11","https://git.kernel.org/stable/c/5699afbff1fa2972722e863906c0320d55dd4d58","https://git.kernel.org/stable/c/d0febad83e29d85bb66e4f5cac0115b022403338","https://git.kernel.org/stable/c/d517cdeb904ddc0cbebcc959d43596426cac40b0","https://git.kernel.org/stable/c/d835fa49d9589a780ff0d001bb7e6323238a4afb"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:10:08.713834912+00:00"},"epss":{"cve":"CVE-2022-50400","score":0.00148,"percentile":0.03986,"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).
