CVE-2023-54296

CVE-2023-54296 concerns the Linux kernel KVM/SMV intrahost migration path. The issue fixed a bug where KVM would grab source vCPUs from the destination VM during intrahost migration, which could cause the guest to fail and the host to crash because the VMSA pointer could be left NULL. The descrip...

UBUNTU-CVE-2024-58083

In the Linux kernel, the following vulnerability has been resolved: KVM: Explicitly verify target vCPU is online in kvmgetvcpu Explicitly verify the target vCPU is fully online prior to clamping the index in kvmgetvcpu. If the index is "bad", the nospec clamping will generate '0', i.e. KVM will...

CVE-2024-58083

CVE-2024-58083 affects the Linux kernel KVM: the target vCPU was not reliably verified online before clamping the index in kvm_get_vcpu(). If the index is bad, nospec clamping could return vCPU0, leading to a use‑after‑free when vCPU0 is dereferenced. The issue is mitigated by ensuring vCPU0 is o...
