If any of those later\nsteps fails, probe returns through the exit label after freeing only the\ncontrol handler.\n\nA failed probe does not call si476x_radio_remove(), so the\nv4l2_device_unregister() there is not reached. This leaves the parent\ndevice reference taken by v4l2_device_register() behind on the error path.\n\nUnregister the V4L2 device in the probe error path after freeing the\ncontrols.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/436a693af04ffb889aaf87cb69ec1f2b21d3569c","https://git.kernel.org/stable/c/4ca9c9f12b1bc341a0a3bbbd2090fd182db53771","https://git.kernel.org/stable/c/64cb15878b35e5574ff4f80a0b613a79e47867ba","https://git.kernel.org/stable/c/730c235d7d2c80a401dac56b0f5066c889aa442d","https://git.kernel.org/stable/c/7cf393f176317a126d71e88e4b6e25e83499b465"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68215","score":0.0022,"percentile":0.1257,"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).
