先行で対応がされていたFragAttacks (CVE-2020-24587, CVE-2020-24588, CVE-2020-26144, CVE-2020-26146, CVE-2020-26147) に関することが主な内容になるかと思います。が国内では技適認証済みのRouterboard製品は多くなく、且つユーザーも限定されると思いますので影響は軽微かと思います。


*) wireless - improved iOS compatibility with HotSpot 2.0 networks;

今回は公式フォーラムを覗いても比較的穏当のようで、IPv6 NDについての不具合が引き続き報告されているようです。
