Also pass the already byte-swapped\nresult variable to BT_DBG instead of the raw __le16 field.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L","score":7.1},"cwes":["CWE-843"],"references":["https://git.kernel.org/stable/c/111f74547eee8cfedfb854284e80f35c8a491186","https://git.kernel.org/stable/c/15145675690cab2de1056e7ed68e59cbd0452529","https://git.kernel.org/stable/c/21d3ba696918d6373233aac0b9d51fcabdedddc0","https://git.kernel.org/stable/c/3b94e62caa1dc1198d0d55d97bd710da1dee15d7","https://git.kernel.org/stable/c/5a1ea296f8589ce8f1e3141b2b123b34ad010e19"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2026-43062","score":0.00216,"percentile":0.11875,"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).
