  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ncxl/region: Fix out-of-bounds access in cxl_cancel_auto_attach()\n\nIn cxl_cancel_auto_attach(), it assumes cxled-\u003epos is a valid index for\naccessing p-\u003etargets[]. However, cxled-\u003epos can be set to negative errno\nin cxl_region_sort_targets() if cxl_calc_interleave_pos() fails. This\ncauses the driver to use a negative index to access p-\u003etargets[],\nresulting in out-of-bounds access.\n\nFix it by walking p-\u003etargets[] instead of using cxled-\u003epos directly.",
