CVE-2020-14646: Oracle VirtualBox LsiLogicSCSI Out-Of-Bounds Write Privilege Escalation Vulnerability
This vulnerability allows local attackers to escalate privileges 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 lsilogicRegisterWrite function.
