A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor emulates a preemption timer for L2 guests when nested (=1) virtualization is enabled This high resolution timer(hrtimer) runs when a L2 guest is active After VM exit, the sync_vmcs12() timer object is stopped The use-after-free occurs if the timer object is fre ...

A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor implements its device control API While creating a device via kvm_ioctl_create_device(), the device holds a reference to a VM object, later this reference is transferred to the caller's file descriptor table If such file descriptor was to be closed, reference co ...
