{"id":"CVE-2026-98909","summary":"net: cpsw_new: unregister devlink on port registration failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: cpsw_new: unregister devlink on port registration failure\n\ncpsw_probe() registers devlink before registering the CPSW ports.\n\nIf cpsw_register_ports() fails, the error path only unregisters the\nnotifiers and then releases the lower level resources. It does not undo\nthe successful cpsw_register_devlink() call, leaving the devlink instance\nand its parameters registered after probe has failed.\n\nAdd a devlink cleanup label for the path where devlink registration has\nalready succeeded, and use it when port registration fails.","modified":"2026-10-28T02:35:03.733133092Z","published":"2026-10-23T11:54:47.326Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98909.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0a44945b0d3422f5d81b49c97e293f3e21a8c585"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2bcf21ede6b097ca96cb1f7679761acca6510555"},{"type":"WEB","url":"https://git.kernel.org/stable/c/43d4af5c5331ea739a49cb1097d41e502ed91ec4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5a5ac0defdd42e566f1c871272370b6a3a8eef5c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8af61d5bd87fd1a3bdc81fe948e7acdc8aa5bcf0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b020390b4ef39adc40c800301042baf812280da1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b64f763b607426ac97e44b114f0b8844ac3b86dd"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98909.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98909"},{"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":"ed3525eda4c4983fb8509e488de0a351788041ba"},{"fixed":"b020390b4ef39adc40c800301042baf812280da1"},{"fixed":"5a5ac0defdd42e566f1c871272370b6a3a8eef5c"},{"fixed":"43d4af5c5331ea739a49cb1097d41e502ed91ec4"},{"fixed":"8af61d5bd87fd1a3bdc81fe948e7acdc8aa5bcf0"},{"fixed":"2bcf21ede6b097ca96cb1f7679761acca6510555"},{"fixed":"0a44945b0d3422f5d81b49c97e293f3e21a8c585"},{"fixed":"b64f763b607426ac97e44b114f0b8844ac3b86dd"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98909.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98909.json"}}],"schema_version":"1.9.2"}
