Kusagadzikana muVMM hypervisor yakagadziriswa neOpenBSD haina kunyatsogadziriswa

Mushure mekuongorora chirongwa cheOpenBSD chakaburitswa fixes kusagadzikana muVMM hypervisor, kuzivikanwa svondo rapfuura, muongorori akawana dambudziko
akaita mhedzisokuti chigamba chakarongerwa vashandisi hachigadzirise dambudziko. Mutsvakurudzi akaratidza kuti dambudziko harisi kuitika nekuda kwekugoverwa kwevaenzi kero dzemuviri (GPA), pamwe chete nemakero emuviri (HPA). Kana yememory peji chimiro ichipfuura, iyo yevaenzi sisitimu inogona kuramba ichinyora zviri mukati meiyo host environment's kernel memory regions.

Kusagadzikana kwakawanikwa naMaxim Villard (Maxime Villard), munyori wekernel kero space randomization mechanism inoshandiswa muNetBSD (KASLR, Kernel Kero Space Layout Randomization) uye gyrevisor NVMM.
