**Name of the Vulnerable Software and Affected Versions** Oracle VM VirtualBox version 7.1.6 **Description** The issue 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 unauthorized creation, deletion, or modification access to critical data or all Oracle VM VirtualBox accessible data, as well as unauthorized access to critical data or complete access to all Oracle VM VirtualBox accessible data. Additionally, it can cause a partial denial of service (partial DOS) of Oracle VM VirtualBox. **Recommendations** For Oracle VM VirtualBox version 7.1.6, update to a version that includes the fix for this issue. At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, consider restricting access to critical data and limiting privileges to minimize the risk of exploitation.

Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified) Description: The vulnerability is related to a register invariant violation in the Linux kernel's eBPF verifier. Specifically, it occurs when the verifier analyzes a branch instruction and splits the register states into true and false branches. The issue arises because the verifier creates a "fake" register initialized to a constant value, which can lead to a range bounds violation. This violation can be exploited to potentially elevate privileges. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
