Google har pr\u00e6senteret initiativet kvmCTF, hvor sikkerhedsforskere kan opn\u00e5 en \u00f8konomisk bel\u00f8nning for at identificere s\u00e5rbarheder i KVM-hyperviseren (Kernel-based Virtual Machine). Googles interesse for KVM skyldes brugen af denne hypervisor i Google Cloud-tjenesten, samt i Android- og ChromeOS-platforme (CrosVM er baseret p\u00e5 KVM). For at opn\u00e5 bel\u00f8nningen skal der demonstreres et angreb p\u00e5 et specielt forberedt CTF (Capture the Flag)-milj\u00f8 baseret p\u00e5 en ny kernel-version af Linux, der k\u00f8rer en virtuel maskine, hvor adgang gives efter ans\u00f8gning. Angriberen tilbydes at udnytte en s\u00e5rbarhed i subsystemet KVM<\/a> i Linux-kernen, der underst\u00f8tter v\u00e6rtsystemet i dette milj\u00f8.<\/p>\n

Der er afsat 250.000 dollars for at opdage en tidligere ukendt s\u00e5rbarhed, der muligg\u00f8r at bryde ud af en virtuel maskine, og 100.000 dollars for s\u00e5rbarheder, der muligg\u00f8r skrivning til et vilk\u00e5rligt hukommelsesomr\u00e5de. For s\u00e5rbarheder, der f\u00f8rer til l\u00e6sning fra et vilk\u00e5rligt hukommelsesomr\u00e5de eller skrivning til tilst\u00f8dende hukommelsesomr\u00e5der, er der afsat 50.000 dollars, 20.000 dollars for en DoS-s\u00e5rbarhed, og 10.000 dollars for l\u00e6sning fra tilst\u00f8dende hukommelse. Bel\u00f8nningen for skrivning eller l\u00e6sning fra et vilk\u00e5rligt hukommelsesomr\u00e5de kan opn\u00e5s ved at \u00e6ndre eller f\u00e5 v\u00e6rdien af en specifik adresse i hukommelsen, og i tilf\u00e6lde af tilst\u00f8dende omr\u00e5der, for fejl, der genkendes af debug-v\u00e6rkt\u00f8jet KASAN (Kernel address sanitizer), s\u00e5som buffer-overl\u00f8b eller adgang til allerede frigivet hukommelse. Bel\u00f8nningen for DoS-s\u00e5rbarheden udbetales ved opdagelse af dereferering af en null peger (null-ptr-deref i KASAN).
