CVE-2025-37849: KVM: arm64: Tear down vGIC on failed vCPU creation

Published May 9, 2025
·
Updated

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 the corresponding memory when the vCPU is destroyed but it can also lead to use-after-free if the redistributor device handling tries to walk into the vCPU.

Add the missing cleanup to kvmarchvcpucreate(), ensuring that the vGIC vCPU structures are destroyed on error.
