Name of the Vulnerable Software and Affected Versions Oracle VM VirtualBox versions prior to 6.1.38

Description The issue is related to insufficient input validation in the PGMPhysRead() function of the Core component in Oracle VM VirtualBox. This allows a high-privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful attacks can result in the takeover of Oracle VM VirtualBox. While the vulnerability is in Oracle VM VirtualBox, attacks may significantly impact additional products.

Recommendations For versions prior to 6.1.38, update to version 6.1.38 or later to resolve the issue. As a temporary workaround, consider restricting access to the PGMPhysRead() function until a patch is available.
