VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is the only professional-quality virtualization solution that is also Open Source.
VirtualBox has received a major update today which fixes crashes related to TPM, graphical issues on Windows 11, and performance problems on Macs. Aside from that, Linux 6.5 and 6.4 are supported.
Ahead of the Linux 6.5-rc2 release tomorrow there was a set of x86/x86_64 kernel changes merged overnight to deal with some weaknesses in the kernel's Control Flow Integrity (kCFI) / FineIBT (Indirect Branch Tracking) code.
Since Linux 5.18 there has been Indirect Branch Tracking (IBT) in the mainline kernel that was contributed by Intel as part of their Control-flow Enforcement Technology (CET)
While Intel Shadow Stack support has been around since Tiger Lake CPUs as part of Intel's Control-flow Enforcement Technology (CET), finally for the Linux 6.4 kernel is this security feature being enabled with the mainline Linux kernel.
