This assumes that the value of \"new\" is\nNULL on the first iteration of the inner loop.\n\nMake sure that this is true in all iterations of the outer\nloop by setting \"new\" to NULL after its value is assigned to \"cur\".\n\nExtend the unittest to detect the double free and add an additional\ntest case that actually triggers this path.","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":["CWE-415"],"references":["https://git.kernel.org/stable/c/26b4d702c44f9e5cf3c5c001ae619a4a001889db","https://git.kernel.org/stable/c/4541004084527ce9e95a818ebbc4e6b293ffca21","https://git.kernel.org/stable/c/4dde83569832f9377362e50f7748463340c5db6b","https://git.kernel.org/stable/c/a0a061151a6200c13149dbcdb6c065203c8425d2","https://git.kernel.org/stable/c/b64d09a4e8596f76d27f4b4a90a1cf6baf6a82f8"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:50:30.954589733+00:00"},"epss":{"cve":"CVE-2023-52679","score":0.00248,"percentile":0.16133,"date":"2026-10-31"},"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).
