## Description

[This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.]  Some Viridian hypercalls can specify a mask of vCPU IDs as an input, in one of three formats.  Xen has boundary checking bugs with all three formats, which can cause out-of-bounds reads and writes while processing the inputs.   * CVE-2025-58147.  Hypercalls using the HV_VP_SET Sparse format can    cause vpmask_set() to write out of bounds when converting the bitmap    to Xen's format.   * CVE-2025-58148.  Hypercalls using any input format can cause    send_ipi() to read d->vcpu[] out-of-bounds, and operate on a wild    vCPU pointer.
