This skips rate_control_deinitialize() and\nleaks the initialized local->rate_ctrl.\n\nFix this by adding a fail_band label that shares the rate-control cleanup\npath before falling through to the remaining teardown.\n\nThe bug was first flagged by an experimental analysis tool we are\ndeveloping for kernel memory-management bugs while analyzing\nv6.13-rc1. The tool is still under development and is not yet publicly\navailable. Manual inspection confirms that the bug is still present in\nv7.1-rc7.\n\nAn x86_64 allyesconfig build showed no new warnings. As we do not have a\nsuitable mac80211 device/driver combination to test with, no runtime\ntesting was able to be performed.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/08b71bd92317f99642b842cfc0d30200868162fc","https://git.kernel.org/stable/c/3d8b9b290421c3cd505fcd2f551f143f8142786a","https://git.kernel.org/stable/c/45e9ac538cdff7bce656d731114a64eda85af0d7","https://git.kernel.org/stable/c/95fc02722edde02946d0d475221f2b2054d3d8ba","https://git.kernel.org/stable/c/a02b52fe54f7b5107aefa1ce28c2f69749c57616"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72004","score":0.0022,"percentile":0.12516,"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).
