This creates a race\ncondition where multiple contexts contending for the lock could overwrite\nthe shared flags variable, potentially corrupting the state for the\ncurrent lock owner.\n\nFix this by using a local stack variable 'flags' to store the IRQ state\ntemporarily.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":4.7},"cwes":["CWE-362"],"references":["https://git.kernel.org/stable/c/24f31be6ad70537fd7706269d99c92cade465a09","https://git.kernel.org/stable/c/4aab0ca0a0f7760e33edcb4e47576064d05128f5","https://git.kernel.org/stable/c/4b58aac989c1e3fafb1c68a733811859df388250","https://git.kernel.org/stable/c/766e243ae8c8b27087a4cc605752c0d5ee2daeab","https://git.kernel.org/stable/c/c2d2cf710dc3ee1a69e00b4ed8de607a92a07889"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2026-23071","score":0.0014,"percentile":0.03356,"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).
