However, during unregistration, the code only removes the\nnode from the hashtable without freeing the associated memory, resulting\nin a memory leak.\n\nResolve the memory leak issue by ensuring the allocated notifier callback\nnode is properly freed after it is removed from the hashtable entry.","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":["CWE-401"],"references":["https://git.kernel.org/stable/c/076fa20b4f5737c34921dbb152f9efceaee571b2","https://git.kernel.org/stable/c/938827c440564b2cf2f9b804d1fe81ce8267eded","https://git.kernel.org/stable/c/a833d31ad867103ba72a0b73f3606f4ab8601719"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:05:46.678065081+00:00"},"epss":{"cve":"CVE-2025-38390","score":0.00187,"percentile":0.08275,"date":"2026-11-01"},"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).
