The driver’s retry logic on subsequent\nbattery property reads can compound this leak, preventing the nvmem\ndevice from ever being freed.\n\nFound by code review.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/700c225d829a1256b59053c34a1a9d1a6ab70b09","https://git.kernel.org/stable/c/a2c14ff63e0e02e3c832385e523e9cc81301171c","https://git.kernel.org/stable/c/a3d81de441233a92ec21469cd0c4eb3c26b95cd8","https://git.kernel.org/stable/c/b56a5cbf8f1f1a5740f1137c89b14d0373309d8d","https://git.kernel.org/stable/c/deaf6b3f8187231ad8f7770b10ed0be2cd47e9b2"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72214","score":0.00215,"percentile":0.11875,"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).
