{
    "lastseen": "",
    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nvhost: move vdpa group bound check to vhost_vdpa\n\nRemove duplication by consolidating these here.  This reduces the\nposibility of a parent driver missing them.\n\nWhile we're at it, fix a bug in vdpa_sim where a valid ASID can be\nassigned to a group equal to ngroups, causing an out of bound write.",
