CVE-2020-14673: Oracle VirtualBox LsiLogicSCSI Time-Of-Check Time-Of-Use 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 lsilogicR3DiagRegDataWrite and lsilogicR3DiagRegDataRead functions. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the hypervisor.
