Release of Oracle VirtualBox 7.1.12 Introduces Key Updates and Security Fixes

On July 15, 2025, Oracle announced the release of its virtualization system, [VirtualBox 7.1.12](https://www.virtualbox.org/wiki/Changelog-7.1#v12). The 7.1 version of VirtualBox was launched in September 2024, and the prior stable build of the project was made available in June 2025.

The installation packages for VirtualBox 7.1.12 have been [released](https://www.virtualbox.org/wiki/Downloads) by Oracle for a variety of operating systems including [RHEL, Fedora, openSUSE, Ubuntu, Debian](https://www.virtualbox.org/wiki/Linux_Downloads), macOS, and Windows.

According to information from OpenNET, the update to VirtualBox 7.1.12 includes [11 modifications](https://www.virtualbox.org/wiki/Changelog-7.1) and resolves [7 vulnerabilities](https://www.oracle.com/security-alerts/cpujul2025.html#AppendixOVIR), three of which have been classified as critical: [CVE-2025-53024](https://www.zerodayinitiative.com/advisories/ZDI-25-601/), [CVE-2025-53027](https://www.zerodayinitiative.com/advisories/ZDI-25-602/), and [CVE-2025-53028](https://www.zerodayinitiative.com/advisories/ZDI-25-600/). One critical issue involved a buffer overflow in the implementation of the VMSVGA virtual device, which could allow code execution at the hypervisor level through guest system manipulations. Significant [updates](https://www.virtualbox.org/wiki/Changelog-7.1) and [enhancements](https://www.neowin.net/software/virtualbox-7110/) in VirtualBox 7.1.12 include:

— Fixes for the host and guest additions on Linux to support the in-development Linux kernel 6.16.
— Resolved issues in Linux guest additions that affected the use of kernels older than version 3.10 and those in the 2.6.x series.
— Addressed a kernel panic issue in Linux-based host systems when using network bridges with the ixgbe driver.
— Fixed nesting issues in the virtual machine manager that occurred during the execution of virtual machines.
— Corrected a NAT problem that caused failures when starting virtual machines with long names.
— Improved the installation of drivers in Windows host additions and added notifications to guest systems regarding AVX/AVX2 extension support when using the Hyper-V hypervisor. Also, resolved a problem that led to a «blue screen of death» when closing the VirtualBox GUI after uninstalling VirtualBox components for the host environment.
— Fixed an issue that made it impossible to launch Windows guest systems when screen output recording was enabled in the settings.
