Medium: qemu

Issue Overview: A bug in QEMU could cause a guest I/O operation otherwise addressed to an arbitrary disk offset to be targeted to offset 0 instead potentially overwriting the VM's boot code. This could be used, for example, by L2 guests with a virtual disk vdiskL2 stored on a virtual disk of an L...

kernel: Kernel: NULL pointer dereference in Intel GVT-g debugfs during device removal

A flaw was found in the Linux kernel's Intel GVT-g Graphics Virtualization Technology debugfs component. When a device is removed through unbinding, the intelgvtdebugfsclean function may attempt to access a debugfs root that has already been deallocated, leading to a NULL pointer dereference. A...

kernel: KVM: nVMX: missing consistency checks for CR0 and CR4

A flaw was found in the KVM's Intel nested virtualization feature nVMX. The effective values of the guest CR0 and CR4 registers could differ from those included in the VMCS12. In rare circumstances i.e., kvmintel module loaded with parameters nested=1 and ept=0 this could allow a malicious guest ...

kernel: KVM: x86/mmu: race condition in direct_page_fault()

A flaw was found in the Linux kernel in the KVM. A race condition in directpagefault allows guest OS users to cause a denial of service host OS crash or host OS memory corruption when nested virtualization and the TDP MMU are enabled...
