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.","published":"2026-08-15T05:57:47.455Z","modified":"2026-08-18T03:56:28.343130683Z","cvss":{"score":8.4,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"7.1.5"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/44b2397eb67b7f728640989a22d062e41f94ab64"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cbda6a2c2bec2a5fb30a2ce85baeab15b5fc7db3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74275.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74275"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-18T03:56:28.343130683Z"}}
