{"id":"CVE-2026-74718","summary":"devlink: fix net namespace reference leak in reload","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndevlink: fix net namespace reference leak in reload\n\ndevlink_nl_reload_doit() calls devlink_netns_get(), which returns a net\nwith a held reference. When the requested namespace differs from the\ncurrent one and the reload action is not DRIVER_REINIT, the function\nreturns -EOPNOTSUPP without releasing the reference. Add the missing\nput_net() on this error path.","modified":"2026-08-24T11:47:21.782519821Z","published":"2026-08-22T15:33:12.106Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74718.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1c4dac9bf1d2ac31da63b794bdec697777cbd0fd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7b02c6d2a3cd2cd669f5c16685779f84328ae60c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7b6552e53426ea0539c667bbc5a524fdf7feae6f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bf0797b92be591ac71d7c0f610e695caca3c72c9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eda60c85b4f4c7d66b7141a5fe020b1a7f395341"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74718.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74718"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"2edd92570441dd33246210042dc167319a5cf7e3"},{"fixed":"7b6552e53426ea0539c667bbc5a524fdf7feae6f"},{"fixed":"bf0797b92be591ac71d7c0f610e695caca3c72c9"},{"fixed":"7b02c6d2a3cd2cd669f5c16685779f84328ae60c"},{"fixed":"eda60c85b4f4c7d66b7141a5fe020b1a7f395341"},{"fixed":"1c4dac9bf1d2ac31da63b794bdec697777cbd0fd"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74718.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.3.0"},{"fixed":"6.6.152"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.104"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.45"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-74718.json"}}],"schema_version":"1.9.0"}
