The issue is related to the Oracle VM VirtualBox product, specifically the Core component. It allows a high-privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox, potentially resulting in unauthorized read access to a subset of Oracle VM VirtualBox accessible data. The vulnerability may significantly impact additional products. The `vmsvgaR3FifoUpdateCursor` function of the virtual machine is associated with a lack of protection of service data, which can be exploited to gain unauthorized access to protected information.
