CVE-2021-32846
HyperKit is a toolkit for embedding hypervisor capabilities in an application. In versions 0.20210107, function pcivtsockproctx in virtio-sock can lead to to uninitialized memory use. In this situation, there is a check for the return value to be less or equal to VTSOCKMAXSEGS, but that check is...
CVE-2021-32844
HyperKit is a toolkit for embedding hypervisor capabilities in an application. In versions 0.20210107 and prior of HyperKit, vipciwrite has is a call to vccfgwrite that does not check for null which when called makes the host crash. This issue may lead to a guest crashing the host causing a denia...
CVE-2021-32845
HyperKit is a toolkit for embedding hypervisor capabilities in an application. In versions 0.20210107 and prior of HyperKit, the implementation of qnotify at pcivtrndnotify fails to check the return value of vqgetchain.
