However, cxled->pos 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->targets[],\nresulting in out-of-bounds access.\n\nFix it by walking p->targets[] instead of using cxled->pos directly.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.4},"cwes":[],"references":["https://git.kernel.org/stable/c/44b2397eb67b7f728640989a22d062e41f94ab64","https://git.kernel.org/stable/c/cbda6a2c2bec2a5fb30a2ce85baeab15b5fc7db3"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-74275","score":0.0018,"percentile":0.07538,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
