Macでもやばいの出てきましたよ。Macの管理者権限を絞っていても、安心しきれない。NEXSIGHT CYBER WIREは、通常のアプリがrootを取得し得るCoreServicesのCVE-2026-43786と、PoC公開を報じている。記事によれば、攻撃にはローカル実行と低い権限が必要。Appleは9月14日のmacOS Tahoe 26.7などで修正したという。外から直接rootを奪う話と、侵入後に権限を上げる話は分けて読みたい。私が気になるのは、管理者権限を渡していないことで安心しているMacと、更新が止まっているMacが重なっていないか。照合の軸は端末台帳のOSバージョン。記事にあるAppleの修正情報への参照まで辿りたい。権限を「渡していない」と「奪われない」は別の話だ。 https://cyber.nexsight.co/articles/2026/09/28/macos-coreservices-cve-2026-43786-poc-root-escalation-2026-09-28/
