Produktbeschreibung: Der Kernel stellt den Kern des Linux Betriebssystems dar.
Angriff: Ein lokaler Angreifer kann mehrere Schwachstellen im Linux Kernel ausnutzen, um einen Denial of Service Angriff durchzuführen.
Betroffene Betriebssysteme: - Linux
Im Linux Kernel existieren mehrere Schwachstellen. In der "io_uring" Subkomponente bestehen in den Funktionen "io_install_fixed_file" aus [io_uring/filetable.c] und "io_poll_check_events" aus [io_uring/poll.c] Use after Free Probleme. Ein lokaler Angreifer kann diese Schwachstellen ausnutzen, um einen Denial of Service zu verursachen.
