An attacker who could start and\ncontrol a VM could possibly use this to expose sensitive information or\nexecute arbitrary code. (CVE-2021-22543)\n\nIt was discovered that the tracing subsystem in the Linux kernel did not\nproperly keep track of per-cpu ring buffer state. A privileged attacker\ncould use this to cause a denial of service.

An attacker\ncould use this to expose sensitive information. (CVE-2021-3732)\n\nAlexey Kardashevskiy discovered that the KVM implementation for PowerPC\nsystems in the Linux kernel did not properly validate RTAS arguments in\nsome situations. An attacker in a guest vm could use this to cause a denial\nof service (host OS crash) or possibly execute arbitrary code.\n(CVE-2021-37576)\n\nIt was discovered that the MAX-3421 host USB device driver in the Linux\nkernel did not properly handle device removal events.
