SUSE CVE-2022-3344
A flaw was found in the KVM's AMD nested virtualization SVM. A malicious L1 guest could purposely fail to intercept the shutdown of a cooperative nested guest L2, possibly leading to a page fault and kernel panic in the host L0...
A flaw was found in the KVM's AMD nested virtualization (SVM). A malicious L1 guest could purposely fail to intercept the shutdown of a cooperative nested guest (L2) possibly leading to a page fault and kernel panic in the host (L0).

kernel: SVM nested virtualization issue in KVM (VMLOAD/VMSAVE)
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB virtual machine control block provided by the L1 guest to spawn/handle a nested guest L2. Due to improper validation of the "virtext" field, this issue could allow a malicious...

kernel: SVM nested virtualization issue in KVM (AVIC support)
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB virtual machine control block provided by the L1 guest to spawn/handle a nested guest L2.

A flaw was found in the way KVM hypervisor handled x2APIC Machine Specific Rregister (MSR) access with nested(=1) virtualization enabled. In that L1 guest could access L0's APIC register values via L2 guest when 'virtualize x2APIC mode' is enabled. A guest could use this flaw to potentially crash the host kernel resulting in DoS issue. Kernel versions from 4.16 and newer are vulnerable to this issue.

USN-4303-1 linux, linux-aws, linux-kvm vulnerability
Paulo Bonzini discovered that the KVM hypervisor implementation in the Linux kernel could improperly let a nested level 2 guest access the resources of a parent level 1 guest in certain situations. An attacker could use this to expose sensitive information...
