The Ethernet connect path stores that\ndevice in mac->mc_dev and keeps it for the lifetime of the connected MAC\nobject.\n\nHowever, the disconnect path only disconnects and closes the MAC before\nfreeing the dpaa2_mac object. It does not drop the endpoint device\nreference stored in mac->mc_dev, so every successful connect leaks that\ndevice reference when the MAC is later disconnected.\n\nDrop the endpoint device reference after closing the MAC and before\nfreeing the dpaa2_mac object.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1974127776da46a000c61f36d4946799ea6d4f51","https://git.kernel.org/stable/c/6b6ffdb9ca4547a3c4c274aa3e25b6c68dbc62e1","https://git.kernel.org/stable/c/915012e923316b8b5d5bf8fc771617b47bd7572d","https://git.kernel.org/stable/c/a3cecf169cc652b558d08661bb6ce55e4c933ec0","https://git.kernel.org/stable/c/b4b201cc93ff70150853aba03e14d314d1980ca0"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:54.990491175+00:00"},"epss":{"cve":"CVE-2026-68331","score":0.00173,"percentile":0.06651,"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).
