  "title": "cxl/region: Validate partition index before array access",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  cxl/region: Validate partition index before array access  construct_region() reads cxled-\u003Epart and uses it to index cxlds-\u003Epart[] without checking for a negative value. If the partition was never resolved, part remains at its initial value of -1, causing an out-of-bounds array access.  Add a guard to return -EBUSY when part is negative.  The check was dropped during a merge.",
