CVE-2021-29795
IBM PowerVM Hypervisor FW860, FW930, FW940, and FW950 could allow a local user to create a specially crafted sequence of hypervisor calls from a partition that could crash the system.
Does this matter?
Lower severity and a low EPSS score (0.24%). Track it; it rarely justifies an emergency change on its own.
