For a\nnon-transmitted MBSSID profile those pointers refer to merged-profile\nstorage owned by the parse object, and the fallback block frees that\nobject at its end. The copied pointers are used afterwards to determine\nthe operating channel, configure bandwidth, and apply HT capabilities.\n\nKeep the fallback parse result alive until association setup finishes.\n\n[reorder variable declaration]","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0878594c5806dd29fa5e16cc026ce19158afdad2","https://git.kernel.org/stable/c/1d9644753d46c86b4e5c05bd6d9d35339ea27331","https://git.kernel.org/stable/c/a10a2f80476d166fd81c361ec0319493671b694e","https://git.kernel.org/stable/c/d0183cd1f6a2dba9e63be20af2f65093c9c8d121","https://git.kernel.org/stable/c/de77b0f68142147e74fac1c497dbe1f93daeeed9"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-98704","score":0.00168,"percentile":0.05984,"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).
