Name of the Vulnerable Software and Affected Versions Oracle VM VirtualBox versions prior to 6.1.28

Description The issue is related to insufficient input validation in the Core component of Oracle VM VirtualBox, which can be exploited to cause a denial of service. A low-privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes can compromise Oracle VM VirtualBox, resulting in the ability to cause a hang or frequently repeatable crash.

Recommendations For versions prior to 6.1.28, update to version 6.1.28 or later to resolve the issue. As a temporary workaround, consider restricting access to the Core component of Oracle VM VirtualBox to minimize the risk of exploitation.
