The switch port connect path stores\nthat device in mac->mc_dev and keeps it for the lifetime of the connected\nMAC object.\n\nHowever, the disconnect path only closes the MAC and frees the dpaa2_mac\nobject. It does not drop the endpoint device reference stored in\nmac->mc_dev, so every successful connect leaks that device reference when\nthe MAC is later disconnected.\n\nDrop the endpoint device reference before freeing the dpaa2_mac object.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0e9a6811eb6198ab17538cd01fa155d133b238ed","https://git.kernel.org/stable/c/196f7301537814bef0f5915f87cd73d6d1235c19","https://git.kernel.org/stable/c/1f4ca61b7a93de3dfa5161bcd38ecb99bb091c38","https://git.kernel.org/stable/c/26ac2d3602347f0377fbcd5214bc28a9d735ae68","https://git.kernel.org/stable/c/4c1eabbef7a1707635652e956e39db1269c3af2b"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68333","score":0.0018,"percentile":0.07603,"date":"2026-11-01"},"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).
