So accessing the disk_bytenr\nmeans we are accessing inline data or in case the inline data is less\nthan 8 bytes we can actually cause an invalid\nmemory access if this inline extent item is the first item in the leaf\nor access metadata from other items.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/08b096c1372cd69627f4f559fb47c9fb67a52b39","https://git.kernel.org/stable/c/39f83f10772310ba4a77f2b5256aaf36994ef7e8","https://git.kernel.org/stable/c/901e581bfc44d181f7d9c3f11880dac3e89deb2e","https://git.kernel.org/stable/c/d948055bd46a9c14d1d4217aed65c5c258c32903","https://git.kernel.org/stable/c/db00636643e66898d79f2530ac9c56ebd5eca369"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:23:35.260773158+00:00"},"epss":{"cve":"CVE-2026-23141","score":0.00143,"percentile":0.03613,"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).
