Ukuba sengozini kwe-VMM hypervisor eyakhiwe yi-OpenBSD akuzange kulungiswe ngokuphelele

Ngemuva kokuhlaziya iphrojekthi ye-OpenBSD ekhishwe ukulungiswa ubungozi ku-VMM hypervisor, ikhonjiwe ngesonto eledlule, umcwaningi owathola inkinga
wenza isiphethoukuthi isiqephu esihlongozwayo kubasebenzisi asiyilungisi inkinga. Umcwaningi ubonise ukuthi inkinga ayenzeki ngenxa yokwabiwa okuhambisanayo kwamakheli ezindawo zesivakashi (GPA), kanye namakheli wendawo (i-HPA). Uma isakhiwo sekhasi lememori sinqamula, isistimu yesivakashi isengabhala ngaphezulu okuqukethwe kwezifunda zenkumbulo ye-kernel yemvelo yomsingathi.

Ukuba sengozini kwatholwa nguMaxim Villard (UMaxime Villard), umbhali we-kernel address space randomization mechanism esetshenziswa ku-NetBSD (KASLR, I-Kernel Address Layout Space Randomization) kanye ne-gyrevisor I-NVMM.
