This happens on the\nnormal registration path when the core checks the voltage constraints\nagainst every selector. TPS652G1 uses the same descriptors and is\naffected too.\n\nUse ARRAY_SIZE() so the count always matches the table.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1ea151615a82fd94f25e38b2cc7eeac49112508b","https://git.kernel.org/stable/c/2f15518682c779b1014552cb2ccb4a2052f85f27","https://git.kernel.org/stable/c/66b7da589b2ce44a02b8387c6160e9254685f34f","https://git.kernel.org/stable/c/f3423b56be12208a393274afb9a5e3d67fc58ce3","https://git.kernel.org/stable/c/f6fbe9c6b39968a7696b9badef4bc29331a6376a"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:28.036610720+00:00"},"epss":{"cve":"CVE-2026-99020","score":0.00168,"percentile":0.06106,"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).
