CVE-2021-32843

HyperKit prior to 0.20210107 contains a null-check flaw in virtio.c where vc_cfgread is called without validating pointers, allowing a guest to crash the host and cause a denial of service. A fix is available in commit df0e46c7dbfd81a957d85e449ba41b52f6f7beb4. Affected users should upgrade to the...

HyperKit 代码问题漏洞

HyperKit is a Moby open source toolkit for embedding virtual machine monitor functionality in applications. A security vulnerability exists in HyperKit 0.20210107 and earlier versions, which stems from a function pcivtsockproctx in virtio-sock that results in uninitialized memory usage, and can b...

CVE-2021-32846 Moby HyperKit uninitialized memory use in virtio-sock pci_vtsock_proc_tx

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...
