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 that the CAN broadcast manger (bcm) protocol\nimplementation in the Linux kernel did not properly initialize memory in\nsome situations. A local attacker could use this to expose sensitive\ninformation (kernel memory). (CVE-2021-34693)\n\nMurray McAllister discovered that the joystick device interface in the\nLinux kernel did not properly validate data passed via an ioctl(). A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code on systems with a joystick device\nregistered.
