Tvrtka Google predstavila je inicijativu kvmCTF, u okviru koje istra\u017eiva\u010di sigurnosti mogu dobiti nov\u010danu nagradu za otkrivanje ranjivosti u hipervizoru KVM (Kernel-based Virtual Machine). Interes Googlea za KVM proizlazi iz kori\u0161tenja ovog hipervizora u usluzi Google Cloud, kao i na platformama Android i ChromeOS (CrosVM se temelji na KVM-u). Da bi se dobila nagrada, mora se demonstrirati provale u posebno pripremljenom CTF (Capture the Flag) okru\u017eenju temeljenom na novom Linux kernelu koji pokre\u0107e virtualnu ma\u0161inu, \u010diji se pristup dodjeljuje na zahtjev. Napada\u010du se nudi mogu\u0107nost iskori\u0161tavanja ranjivosti u podsustavu KVM<\/a> u Linux kernelu, koji omogu\u0107ava rad host-sustava u ovom okru\u017eenju.<\/p>\n

Za otkrivanje ranjivosti koja ranije nije bila poznata, koja omogu\u0107ava izlazak iz virtualne ma\u0161ine, predvi\u0111ena je isplata od 250 tisu\u0107a dolara, a za ranjivosti koje omogu\u0107avaju zapis u proizvoljno podru\u010dje memorije \u2014 100 tisu\u0107a dolara. Za ranjivosti koje dovode do \u010ditanja iz proizvoljnog podru\u010dja memorije ili zapisivanja u susjedna podru\u010dja memorije, predvi\u0111ena je isplata od 50 tisu\u0107a dolara, za DoS ranjivost \u2014 20 tisu\u0107a dolara, a za \u010ditanje iz susjednog podru\u010dja memorije \u2014 10 tisu\u0107a dolara. Nagradu za zapis ili \u010ditanje proizvoljnog podru\u010dja memorije mogu\u0107e je dobiti promjenom ili dobivanjem vrijednosti odre\u0111enog adresa u memoriji, a u slu\u010daju susjednog podru\u010dja \u2014 za gre\u0161ke koje prepoznaje alat za debagiranje KASAN (Kernel Address Sanitizer), kao \u0161to su prelivanje bafer memorije ili pristup ve\u0107 oslobodjenom podru\u010dju memorije. Nagrade za DoS ranjivost ispla\u0107uju se prilikom otkrivanja dereferenciranja nultog pokaziva\u010da (null-ptr-deref u KASAN).
