This ensures that the memory won't leak, whatever way the\ncontrol gets destroyed.\n\nThe original implementation didn't actually remove the ALSA\ncontrols in hda_cs_dsp_control_remove(). It only freed the internal\ntracking structure. This meant it was possible to remove/unload the\namp driver while leaving its ALSA controls still present in the\nsoundcard. Obviously attempting to access them could cause segfaults\nor at least dereferencing stale pointers.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-401"],"references":["https://git.kernel.org/stable/c/172811e3a557d8681a5e2d0f871dc04a2d17eb13","https://git.kernel.org/stable/c/191dc1b2ff0fb35e7aff15a53224837637df8bff","https://git.kernel.org/stable/c/3291486af5636540980ea55bae985f3eaa5b0740","https://git.kernel.org/stable/c/6e359be4975006ff72818e79dad8fe48293f2eb2","https://git.kernel.org/stable/c/172811e3a557d8681a5e2d0f871dc04a2d17eb13"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:52:00.836172422+00:00"},"epss":{"cve":"CVE-2024-38388","score":0.00231,"percentile":0.14057,"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).
