These\nunbalanced regulator_enable() calls cause the regulator to never\nbe turned off and trigger the following WARN() on driver unbind:\n\nWARNING: CPU: 1 PID: 1724 at drivers/regulator/core.c:2396 _regulator_put\n\nFix this by making lis3lv02d_i2c_resume() mirror the new suspend().","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/4154e767354140db7804207117e7238fb337b0e7","https://git.kernel.org/stable/c/997ca415384612c8df76d99d9a768e0b3f42b325","https://git.kernel.org/stable/c/ac3e0384073b2408d6cb0d972fee9fcc3776053d","https://git.kernel.org/stable/c/f6df761182fc953907b18aba5049fc2a044ecb45","https://git.kernel.org/stable/c/4154e767354140db7804207117e7238fb337b0e7"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:50:30.954589733+00:00"},"epss":{"cve":"CVE-2024-35824","score":0.00211,"percentile":0.11418,"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).
