The name allocated by dev_set_name() is leaked.\n2. The parent of device is not NULL, device_unregister() is called\n   in zynqmp_ipi_free_mboxes(), it will lead a kernel crash because\n   of removing not added device.\n\nCall put_device() to give up the reference, so the name is freed in\nkobject_cleanup(). Add device registered check in zynqmp_ipi_free_mboxes()\nto avoid null-ptr-deref.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/3fcf079958c00d83c51e4f250abf2c77fe9cc1b9","https://git.kernel.org/stable/c/4f05d8e2fb3ab702c2633a74571e1b31cb579985","https://git.kernel.org/stable/c/a39b4de0804f9fe0ae911b359ffd4afe7d9d933b","https://git.kernel.org/stable/c/a6792a0cdef0b1c2d77920246283a72537e60e94","https://git.kernel.org/stable/c/b3a5c76f61e2b380e29dfc6705854ca1ee85501d"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:16:40.427100871+00:00"},"epss":{"cve":"CVE-2022-50672","score":0.00244,"percentile":0.15705,"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).
