This underflows the refcount of the VIP device's\nOF node when endpoint parsing fails on a malformed device tree.\n\nThe only reference the function takes on np is the success-path\nof_node_get() stored in vip->chan.of_node, and that one is already\nreleased by the tegra_vip_init() error path and by tegra_vip_exit().\n\nReturn errors directly instead of jumping to the bogus cleanup label.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1295ba29ac590bbb5c4a586afd408018168af10b","https://git.kernel.org/stable/c/656d047dc0c29c0964d840217a0593f16aa9bc5e","https://git.kernel.org/stable/c/7393372f79db940acff206b43e2905685a0c57ad","https://git.kernel.org/stable/c/a3783800c9475fa58b8db0885893f96a23f949da","https://git.kernel.org/stable/c/fc9937019cf7e2fe4e29f9341e6400bcd2cde721"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-93223","score":0.00168,"percentile":0.06042,"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).
