The issue is related to the use of memory after it has been freed, which can allow an attacker to elevate their privileges. This is an elevation-of-privilege vulnerability that affects the system. The vulnerability is also described as a use-after-free local privilege escalation issue in Microsoft Windows DirectComposition.

Name of the Vulnerable Software and Affected Versions: Oracle VM VirtualBox versions prior to 7.0.16 Description: The issue is related to the use of memory after it has been freed, which can allow an attacker to disclose protected information. A low-privileged attacker with logon access to the infrastructure where Oracle VM VirtualBox executes can exploit this issue to compromise Oracle VM VirtualBox. Successful attacks can result in unauthorized access to critical data or complete access to all Oracle VM VirtualBox accessible data. Recommendations: For versions prior to 7.0.16, update to version 7.0.16 or later to resolve the issue. At the moment, there is no information about additional mitigation measures.

The issue is related to a buffer overflow vulnerability in the Core component of Oracle VM VirtualBox, which can be exploited to execute arbitrary code and elevate privileges. This vulnerability can be easily exploited by a low-privileged attacker with logon access to the infrastructure where Oracle VM VirtualBox is executed, potentially leading to the compromise of Oracle VM VirtualBox and impacting additional products.

The issue is related to insufficient access control in the Win32k component of the Windows operating system. It allows an attacker to elevate their privileges. There is no information about the estimated number of potentially affected devices worldwide or real-world incidents where this issue was exploited.

The issue is related to an off-by-one heap-overflow vulnerability in the SVGA device, which can be exploited by a malicious actor with local access to a virtual machine with 3D graphics enabled, potentially allowing code execution on the hypervisor from a virtual machine. Exploitation requires additional conditions beyond the attacker's control. The vulnerability is also described as a buffer overflow in dynamic memory when processing SVGA3D commands.

The issue is related to a use-after-free vulnerability in the SVGA device, specifically when handling the SVGA DXInvalidateContext command. This vulnerability can be exploited by a malicious actor with local access to a virtual machine that has 3D graphics enabled, potentially allowing them to execute code on the hypervisor from the virtual machine.
