CVE-2026-97423

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