Currently, in this scenario the freeze listener\nremains in the freeze_listeners rbtree and in the remote node's freeze\nlistener list, even though the ref for which the listener is registered\nis gone. This could potentially lead to a memory leak due to a refcount\ncycle. Thus, remove the freeze listener in this scenario.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0644da3621ddd8e146280675a2a31d1e06634a1d","https://git.kernel.org/stable/c/91b27f8172cdbf265240104772fd042a461a7767","https://git.kernel.org/stable/c/bc4a9828897871ff3e5a1f8a1d346decbf4ee95e"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:46:40.600842820+00:00"},"epss":{"cve":"CVE-2026-64466","score":0.00206,"percentile":0.10719,"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).
