Overview

CVE-2026-74275 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 8.4 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.4, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

cxl/region: Fix out-of-bounds access in cxl_cancel_auto_attach()

In cxl_cancel_auto_attach(), it assumes cxled->pos is a valid index for

accessing p->targets[]. However, cxled->pos can be set to negative errno

in cxl_region_sort_targets() if cxl_calc_interleave_pos() fails. This

causes the driver to use a negative index to access p->targets[],

resulting in out-of-bounds access.

Fix it by walking p->targets[] instead of using cxled->pos directly.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
