Firma Google zaprezentowa\u0142a inicjatyw\u0119 kvmCTF, w ramach kt\u00f3rej badacze bezpiecze\u0144stwa mog\u0105 otrzyma\u0107 nagrody pieni\u0119\u017cne za wykrywanie luk w hiperwizyjnej KVM (Kernel-based Virtual Machine). Zainteresowanie Google KVM wynika z wykorzystania tego hiperwizora w us\u0142udze Google Cloud, a tak\u017ce na platformach Android i ChromeOS (CrosVM oparty jest na KVM). Aby otrzyma\u0107 nagrod\u0119, nale\u017cy zademonstrowa\u0107 wykorzystanie luki w specjalnie przygotowanym \u015brodowisku CTF (Capture the Flag) opartym na \u015bwie\u017cym j\u0105drze Linuxa, wirtualizuj\u0105cym maszyn\u0119, do kt\u00f3rej dost\u0119p przyznawany jest na wnioski.

Za wykrycie wcze\u015bniej nieznanej luki, kt\u00f3ra umo\u017cliwia wydostanie si\u0119 z wirtualnej maszyny, przewidziana jest nagroda w wysoko\u015bci 250 tysi\u0119cy dolar\u00f3w, a za luki umo\u017cliwiaj\u0105ce zapis do dowolnego obszaru pami\u0119ci \u2014 100 tysi\u0119cy dolar\u00f3w. Za luki prowadz\u0105ce do odczytu z dowolnego obszaru pami\u0119ci lub zapisu do s\u0105siednich obszar\u00f3w pami\u0119ci oferuje si\u0119 nagrod\u0119 w wysoko\u015bci 50 tysi\u0119cy dolar\u00f3w, za luk\u0119 DoS \u2014 20 tysi\u0119cy dolar\u00f3w, a za odczyt z s\u0105siedniego obszaru pami\u0119ci \u2014 10 tysi\u0119cy dolar\u00f3w. Nagrod\u0119 za zapis lub odczyt dowolnego obszaru pami\u0119ci mo\u017cna otrzyma\u0107 za zmian\u0119 lub uzyskanie warto\u015bci konkretnego adresu w pami\u0119ci, a w przypadku s\u0105siedniego obszaru \u2014 za b\u0142\u0119dy wykrywane przez narz\u0119dzie debuguj\u0105ce KASAN (Kernel address sanitizer), takie jak przepe\u0142nienie bufora lub odwo\u0142anie do ju\u017c zwolnionego obszaru pami\u0119ci. Nagroda za luk\u0119 DoS jest wyp\u0142acana przy wykryciu dereferencji wska\u017anika zerowego (null-ptr-deref w KASAN).
