**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
An issue exists in the KVM nSVM component where the VMLOAD/VMSAVE emulation code fails to consistently use `vmcb01`. When VMSAVE/VMLOAD is executed by an L2 guest and is not intercepted by L1, the system mistakenly uses `vmcb02` instead of `vmcb01` for fields controlled by these instructions.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
