Da die Anzahl der im Linux-Kern unterst\u00fctzten Modi zur Bek\u00e4mpfung von CPU-Schwachstellen 15 erreicht hat und es zunehmend kompliziert wird, alle Schwachstellen in der Kernel-Befehlszeile aufzulisten, hat ein Kernel-Entwickler von AMD vorgeschlagen, von der Anpassung der Blockierung spezifischer Schwachstellen zu einer Auswahl der Blockierung von Angriffsvektoren \u00fcberzugehen. <\/p>\n

Die Blockierungsmethoden sollen je nach Art des Isolationsversto\u00dfes aktiviert werden: zwischen Benutzer und Kernel (mitigate_user_kernel), zwischen Benutzern (mitigate_user_user), zwischen Gastbetriebssystem und Host-Umgebung (mitigate_guest_host), zwischen verschiedenen Gastbetriebssystemen (mitigate_guest_guest) und zwischen verschiedenen Threads (mitigate_cross_thread). <\/p>\n

Der vorgeschlagene Ansatz erm\u00f6glicht es, nur den Schutz f\u00fcr solche Vulnerabilit\u00e4tsklassen zu aktivieren, die den Benutzer tats\u00e4chlich betreffen. Beispielsweise k\u00f6nnen Besitzer von Cloud-Umgebungen die Modi mitigate_guest_host und mitigate_guest_guest aktivieren, woraufhin Methoden zum Schutz vor den Schwachstellen BHI, GD, L1TF, MDS, MMIO, Retbleed, RFDS, Spectre_v2, SRBDS, SRSO und TAA aktiviert werden. =============== ============== ============ ============= ============== ============ Schwachstelle Benutzer-zu-Kernel Benutzer-zu-Benutzer Gast-zu-Host Gast-zu-Gast Cross-Thread =============== ============== ============ ============= ============== ============ BHI X X GDS X X X X L1TF X X MDS X X X X X MMIO X X X X X Meltdown X Retbleed X X X RFDS X X X X Spectre_v1 X Spectre_v2 X X Spectre_v2_user X X SRBDS X X X X SRSO X X SSB TAA X X X X X
