Both go on to\nsnd_soc_enum_item_to_val(), which indexes e->values with no bound of\nits own, so an enum with a value table reads one element past the end.\n\nThe indexing arrived with the MUX consolidation, which relaxed the\nitem[1] check in the same hunk.  The value MUX handler it deleted used\n>= there, and the snd_soc_put_enum_double() in soc-ops.c still does.\n\nOnly adav80x pairs a value table with two shifts, and its second\nchannel looks accidental, but the control does report two values.\nWriting three into it reads off the end of adav80x_mux_values.  The\ncore catches that only under CONFIG_SND_CTL_INPUT_VALIDATION, which\ndefaults off.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/10a36512c21f861a03fba461a7ead09023df9c1b","https://git.kernel.org/stable/c/14511c9b54ceeeef487409d73947c89ee8563590","https://git.kernel.org/stable/c/32fc048391112559c34cb88d13594546939a4cd6","https://git.kernel.org/stable/c/496081b4edc1f6e662418831c5b14cddd8d7920c","https://git.kernel.org/stable/c/55126ef66298e43c69f192acebae8c7cc0022cf6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90068","score":0.00216,"percentile":0.11963,"date":"2026-10-25"},"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).
