The\nrwsem is taken just before that check, hence the rest context should\nbe covered by that properly.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/084d5d44418148662365eced3e126ad1a81ee3e2","https://git.kernel.org/stable/c/20c52a70414095447da1be076f492cc7a6dce7cf","https://git.kernel.org/stable/c/8c097cf736993454acf3f711a3b376d6c7ad8965","https://git.kernel.org/stable/c/ae583f113d15fa97e5234133c20d09f8e6214e47","https://git.kernel.org/stable/c/e6645e625480cdf1079a4265f758d13b70721029"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-43126","score":0.00163,"percentile":0.05481,"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).
