Linux Kernel: Schwachstelle ermöglicht Offenlegung von Informationen
Severity
Mittel
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 entfernter Angreifer kann eine Schwachstelle im Linux Kernel ausnutzen, um Informationen offenzulegen.
Betroffene Betriebssysteme: - Linux
Es besteht eine Schwachstelle im Linux-Kernel im der "Page-Cache" Implementierung in "mincore()" in [mm/mincore.c]. Ein lokaler Angreifer kann die Zugriffsmuster auf den Page-Cache bei anderen Prozessen beobachten, um Informationen offenzulegen. Eine eingeschränkte Remote-Ausnutzung ist ebenfalls möglich. Die "Page-Cache" Implementierungen anderer Betriebssysteme können ebenfalls von dieser Seitenkanal-Schwachstelle betroffen sein.
