{"id":"CVE-2025-68246","summary":"ksmbd: close accepted socket when per-IP limit rejects connection","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: close accepted socket when per-IP limit rejects connection\n\nWhen the per-IP connection limit is exceeded in ksmbd_kthread_fn(),\nthe code sets ret = -EAGAIN and continues the accept loop without\nclosing the just-accepted socket. That leaks one socket per rejected\nattempt from a single IP and enables a trivial remote DoS.\n\nRelease client_sk before continuing.\n\nThis bug was found with ZeroPath.","modified":"2026-04-16T04:40:55.448267574Z","published":"2025-12-16T14:21:23.551Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68246.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/35521b5a7e8a184548125f4530552101236dcda1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4587a7826be1ae0190dba10ff70b46bb0e3bc7d3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5746b2a0f5eb3d79667b3c51fe849bd62464220e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7a3c7154d5fc05956a8ad9e72ecf49e21555bfca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/98a5fd31cbf72d46bf18e50b3ab0ce86d5f319a9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68246.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68246"},{"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":"0626e6641f6b467447c81dd7678a69c66f7746cf"},{"fixed":"7a3c7154d5fc05956a8ad9e72ecf49e21555bfca"},{"fixed":"5746b2a0f5eb3d79667b3c51fe849bd62464220e"},{"fixed":"4587a7826be1ae0190dba10ff70b46bb0e3bc7d3"},{"fixed":"35521b5a7e8a184548125f4530552101236dcda1"},{"fixed":"98a5fd31cbf72d46bf18e50b3ab0ce86d5f319a9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68246.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.15.0"},{"fixed":"6.1.159"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.117"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.59"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.17.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-68246.json"}}],"schema_version":"1.7.5"}
