Google esitas algatuse kvmCTF, mille raames saavad turvauuringute teadlased rahalise auhinna KVM (Kernel-based Virtual Machine) h\u00fcperviisori haavatavuste tuvastamise eest. Google'i huvi KVM-i vastu tuleneb selle h\u00fcperviisori kasutamisest Google Cloud teenustes ning Androidi ja ChromeOS platvormides (CrosVM p\u00f5hineb KVM-il). Auhinna saamiseks peab olema demonstreeritud h\u00e4kkimine spetsiaalselt ettevalmistatud CTF (Capture the Flag) keskkonda, mis p\u00f5hineb v\u00e4rskel Linuxi tuumal, mis t\u00f6\u00f6tab virtuaalmasinas, millele juurdep\u00e4\u00e4su antakse taotluse kaudu. R\u00fcndajale pakutakse v\u00f5imalust \u00e4ra kasutada haavatavust tuumade alams\u00fcsteemis. KVM<\/a> Linuxi tuumas, mis tagab host-s\u00fcsteemi t\u00f6\u00f6 antud keskkonnas.<\/p>\n

Eelnevalt teadmata haavatavuse tuvastamise eest, mis v\u00f5imaldab virtuaalmasinast v\u00e4lja tulla, makstakse 250 000 dollari suurune tasu, samas kui haavatavuste eest, mis v\u00f5imaldavad kirjutada suvalisse m\u00e4lu piirkonda, on tasu 100 000 dollarit. Haavatavuste eest, mis v\u00f5ivad viia suvalisest m\u00e4lu piirkonnast lugemiseni v\u00f5i kirjutamiseni k\u00fclgnevatesse m\u00e4lu piirkondadesse, on v\u00e4lja kuulutatud tasu 50 000 dollarit, DoS-haavatavuse eest - 20 000 dollarit, ning k\u00fclgnevate m\u00e4lu piirkondade lugemise eest - 10 000 dollarit. Tasusummat suvalise m\u00e4lu piirkonna kirjutamise v\u00f5i lugemise eest v\u00f5ib saada, muutes v\u00f5i saades konkreetse aadressi v\u00e4\u00e4rtuse m\u00e4lus, ja k\u00fclgnevate piirkondade puhul - KASAN (Kernel address sanitizer) silumise t\u00f6\u00f6riista tunnustatud vigade, nagu m\u00e4lupuhvri \u00fclet\u00e4itumine v\u00f5i juba vabastatud m\u00e4lu piirkonna juurde p\u00e4\u00e4semise eest. DoS-haavatavuse tasu makstakse v\u00e4lja, kui tuvastatakse nullviitme de-referents (null-ptr-deref KASAN-is).
