If deletion fails, tca_action_gd() calls\ntcf_action_put_many() to release the remaining references, but its\ntcf_act_for_each_action() iterator stops at the first NULL slot.\n\nWhen a batch stops at an action bound to a filter, this leaks a\nreference on each subsequent action. A later delete of an unbound\naction can then return success without removing it from the IDR.\n\nWalk the full array in tcf_action_put_many() and skip NULL slots to\nrelease the references held on the unprocessed actions.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1be63e4579af408d596f0f3165faf1a880631d3b","https://git.kernel.org/stable/c/57b477e46ef2df3483f3488cc713c61c4b384aab","https://git.kernel.org/stable/c/6e05e46fa821a5c1b281355f1f622ac76cb6080a","https://git.kernel.org/stable/c/9eaba16f1b6ee19b249e6afd82c27f958d441458"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-98235","score":0.00168,"percentile":0.06017,"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).
