Overview
CVE-2026-97423 is a known-severity vulnerability. It was published on September 24, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
cxl/region: Validate partition index before array access
construct_region() reads cxled->part and uses it to index
cxlds->part[] 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.
