Summary
[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.
