Im Interface der asynchronen Ein- und Ausgabe io_uring, das vom Linux-Kernel bereitgestellt wird, wurde eine Sicherheitsanf\u00e4lligkeit (CVE-2025-39698) entdeckt, die es einem nicht privilegierten Benutzer erm\u00f6glicht, seinen Code auf Kernel-Ebene auszuf\u00fchren. Die Sicherheitsanf\u00e4lligkeit resultiert aus dem Fehlen einer \u00dcberpr\u00fcfung der Existenz eines Objekts vor der Ausf\u00fchrung von Operationen mit diesem Objekt. <\/p>\n

Die Sicherheitsanf\u00e4lligkeit wurde in den Kernel-Updates 6.16.4 und 6.12.44 behoben. Den Zustand der aktuellen Version des Pakets oder die Vorbereitung eines Fixes in den Distributionen k\u00f6nnen Sie auf den folgenden Seiten \u00fcberpr\u00fcfen (wenn die Seite nicht verf\u00fcgbar ist, haben die Entwickler der Distribution das Problem m\u00f6glicherweise noch nicht behandelt): Debian, Ubuntu, Fedora, SUSE\/openSUSE, RHEL, Gentoo und Arch.
