Linux Kernel Heap Buffer Overflow DoS
The vulnerability of the kvmvmioctlcreatevcpu function in the Linux operating system arises from a race condition. Exploiting this vulnerability could allow an attacker to trigger a service failure...
DEBIAN-CVE-2025-38455
In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Reject SEV-ES intra host migration if vCPU creation is in-flight Reject migration of SEV-ES state if either the source or destination VM is actively creating a vCPU, i.e. if kvmvmioctlcreatevcpu is in the section betwee...
CVE-2025-38455 KVM: SVM: Reject SEV{-ES} intra host migration if vCPU creation is in-flight
In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Reject SEV-ES intra host migration if vCPU creation is in-flight Reject migration of SEV-ES state if either the source or destination VM is actively creating a vCPU, i.e. if kvmvmioctlcreatevcpu is in the section betwee...
CVE-2025-38455 KVM: SVM: Reject SEV{-ES} intra host migration if vCPU creation is in-flight
In the Linux kernel, the following vulnerability has been resolved: KVM: SVM: Reject SEV-ES intra host migration if vCPU creation is in-flight Reject migration of SEV-ES state if either the source or destination VM is actively creating a vCPU, i.e. if kvmvmioctlcreatevcpu is in the section betwee...
CVE-2025-38455
CVE-2025-38455 is a Linux kernel/KVM vulnerability in the KVM: SVM path. The issue occurs during SEV{-ES} intra-host migration when a vCPU is being created (in-flight) on either source or destination VM, where SEV{-ES} state can be toggled to non-SEV{-ES} in the destination. This can lead to a cr...

CVE-2025-37849
In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Tear down vGIC on failed vCPU creation If kvmarchvcpucreate fails to share the vCPU page with the hypervisor, we propagate the error back to the ioctl but leave the vGIC vCPU data initialised. Note only does this leak...
CVE-2025-37849
CVE-2025-37849 affects the Linux kernel KVM arm64; the issue occurs when kvm_arch_vcpu_create() fails to share the vCPU page with the hypervisor, leaving vGIC vCPU data initialised. This can leak memory on vCPU destruction and may cause use-after-free in redistributor handling. The fix adds prope...
