Notes
Das BSI ist als Anbieter für die eigenen, zur Nutzung bereitgestellten Inhalte nach den allgemeinen Gesetzen verantwortlich. Nutzerinnen und Nutzer sind jedoch dafür verantwortlich, die Verwendung und/oder die Umsetzung der mit den Inhalten bereitgestellten Informationen sorgfältig im Einzelfall zu prüfen.
Produktbeschreibung: Der Kernel stellt den Kern des Linux Betriebssystems dar.
Angriff: Ein lokaler Angreifer kann eine Schwachstelle im Linux Kernel ausnutzen, um Informationen offenzulegen.
Betroffene Betriebssysteme: - Linux
Im Linux-Kernel besteht eine Schwachstelle bei der Reaktivierung des Systems aus "Suspend-to-RAM". Modellspezifische Register (MSRs), die das "spekulative Ausführungsverhalten" der CPU steuern, werden bei der Boot-CPU nicht wiederhergestellt. Dies führt zu einem fehlenden Schutz gegen Schwachstellen in der spekulativen Ausführung bei einigen CPU-Modellen. Infolgedessen kann ein lokaler Angreifer einige CPU-Schwachstellen, falls vorhanden, ausnutzen, um Informationen offenzulegen.
