This is happening in the DRM framework for example.\n\nWe should thus call devres_release_all() in the device_del() function to\nmake sure that the device-managed actions are properly executed when the\ndevice is unregistered, even if it has neither a bus nor a driver.\n\nThis is effectively the same change than commit 2f8d16a996da (\"devres:\nrelease resources on device_del()\") that got reverted by commit\na525a3ddeaca (\"driver core: free devres in device_release\") over\nmemory leaks concerns.\n\nThis patch effectively combines the two commits mentioned above to\nrelease the resources both on device_del() and device_release() and get\nthe best of both worlds.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-415"],"references":["https://git.kernel.org/stable/c/297992e5c63528e603666e36081836204fc36ec9","https://git.kernel.org/stable/c/3bcc4c2a096e8342c8c719e595ce15de212694dd","https://git.kernel.org/stable/c/699fb50d99039a50e7494de644f96c889279aca3","https://git.kernel.org/stable/c/83e2ec36a92432e9445e853c12becbbae353b511","https://git.kernel.org/stable/c/b9ef4b0aa91d2f9f5951faafdbbd47cf01799ec3"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:11:26.888974865+00:00"},"epss":{"cve":"CVE-2023-53596","score":0.00158,"percentile":0.04931,"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).
