Ku-hypervisor ehlinzekwe yi-OpenBSD ikhonjiwe , okuvumela, ngokukhohlisa ohlangothini lwesistimu yesivakashi, ukubhala phezu kokuqukethwe kwezindawo zememori ze-kernel yendawo yokusingatha. Inkinga ibangelwa ukuthi ingxenye yamakheli ezindawo zesivakashi (i-GPA, Ikheli Lendawo Yezihambeli) lifakwe imephu ku-kernel virtual address space (KVA), kodwa i-GPA ayinakho ukuvikelwa kokubhala okusetshenziswa ezindaweni ze-KVA ezimakwe njengefundwa kuphela. . Ngenxa yokushoda kokuhlola okudingekayo kumsebenzi we-evmm_update_pvclock(), kuyenzeka ukudlulisa amakheli e-KVA ohlelo lomsingathi kukholi ye-pmap futhi ubhale phezu okuqukethwe kwememori ye-kernel.
Isibuyekezo: Abathuthukisi be-OpenBSD bakhululiwe ukulungisa ubungozi.
