"details": "Maxim Levitsky and Paolo Bonzini discovered that the KVM hypervisor\nimplementation for AMD processors in the Linux kernel allowed a guest VM to\ndisable restrictions on VMLOAD/VMSAVE in a nested guest. An attacker in a\nguest VM could use this to read or write portions of the host's physical\nmemory. (CVE-2021-3656)\n\nMaxim Levitsky discovered that the KVM hypervisor implementation for AMD\nprocessors in the Linux kernel did not properly prevent a guest VM from\nenabling AVIC in nested guest VMs. An attacker in a guest VM could use this\nto write to portions of the host's physical memory. (CVE-2021-3653)\n\nNorbert Slusarek discovered a race condition in the CAN BCM networking\nprotocol of the Linux kernel leading to multiple use-after-free\nvulnerabilities. A local attacker could use this issue to execute arbitrary\ncode. (CVE-2021-3609)\n",
