A corrupted attribute can drive that addition past\nthe representable range.\n\nOne corrupt runlist shape sets the accumulated LCN to S64_MAX and\nthen adds a delta of 1 in the next mapping-pairs entry.\n\nSigned overflow is undefined and can turn an invalid runlist into a\ndifferent set of physical clusters.\n\nCheck the LCN addition for overflow before storing the next run.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":[],"references":["https://git.kernel.org/stable/c/6626fb859f4c4772f2f59751d23937716e03f98f","https://git.kernel.org/stable/c/7fb64788812d137b37f6d8724e1e41c624c1e814","https://git.kernel.org/stable/c/7ffa8f3d30236e0ab897c30bdb01224ff1fe1c89","https://git.kernel.org/stable/c/ec4f061f2219e0f0c6465d56d0380bf749235a53"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-72200","score":0.00671,"percentile":0.51747,"date":"2026-10-25"},"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).
