Name of the Vulnerable Software and Affected Versions: Oracle VM VirtualBox versions prior to 7.0.16 Description: The issue is related to insufficient input validation in the Core component of Oracle VM VirtualBox, allowing a low-privileged attacker with logon access to the infrastructure to compromise Oracle VM VirtualBox. Successful attacks can result in unauthorized ability to cause a hang or frequently repeatable crash of Oracle VM VirtualBox, potentially impacting additional products. Recommendations: Update to version 7.0.16 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.

**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 6.2.8 **Description** An issue was discovered in the Linux kernel related to the lack of consistency checks for CR0 and CR4 in nVMX on x86 64. This issue is associated with the function nested vmx check guest state() in the arch/x86/kvm/vmx/nested.c module of the KVM subsystem. Exploitation of this issue may allow an attacker to cause a denial of service in the guest operating system. **Recommendations** For versions prior to 6.2.8, update to version 6.2.8 or later to resolve the issue. As a temporary workaround, consider restricting the use of the nested vmx check guest state() function until a patch is available.
