CVE-2020-14629: Oracle VirtualBox virtio-net Uninitialized Memory Information Disclosure Vulnerability
First published: Wed Jul 15 2020(Updated: )
This vulnerability allows local attackers to disclose sensitive information on affected installations of Oracle VirtualBox. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the virtio-net component. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the hypervisor.
