The PMIC GLINK client stays on the client list until\nits devres release action runs, so a PDR notification can keep queueing\nthe work, and a pending or running worker can access battmgr after devres\nfrees it.\n\nMake enable_work device-managed with devm_work_autocancel(), registered\nbefore the PMIC GLINK client is allocated. The devres cleanup then\nreleases the client first, so no further notification can queue the work,\nand cancels the work before battmgr is freed.\n\nThis issue was found by an in-house static analysis tool.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/06618447029c6dddaa02f6e9528efe5dd49fc329","https://git.kernel.org/stable/c/35964ed01e10b61a30066b0c568aa0e0e8fb6432","https://git.kernel.org/stable/c/49fbcd3da2958159370d25dafbf736e654a4d59b","https://git.kernel.org/stable/c/4e40befedfc8ed86f44e1f81df92d13c149c9f8d","https://git.kernel.org/stable/c/77fefca305db44b0edd3fcdb52d781771c1ce366"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-89467","score":0.00168,"percentile":0.06155,"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).
