{"id":"CVE-2026-97411","summary":"net: ibm: emac: mal: fix potential system hang in mal_remove()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ibm: emac: mal: fix potential system hang in mal_remove()\n\nnapi_disable() is not idempotent and calling it on an already-disabled\nor unenabled NAPI context will cause the kernel to spin indefinitely\nwaiting for the NAPI_STATE_SCHED bit to clear.\n\nIn mal_remove(), napi_disable() is called unconditionally. If no MACs were\nregistered, NAPI was never enabled. Also, if they were registered but\nsubsequently unregistered, NAPI was already disabled in\nmal_unregister_commac(). In either case, calling napi_disable() causes\nthe kernel to hang upon module removal.\n\nFix this by only calling napi_disable() in mal_remove() if the commac list\nis not empty (which implies NAPI is enabled).","modified":"2026-09-26T03:48:27.092174173Z","published":"2026-09-24T16:03:17.967Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97411.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/7c5d41f87f079990bf241359e3c1332d8d10fe87"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c4cb9a728df66c46067b26263f5beb633aae4087"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f6c1aad9b35fa083f48ce0c5926204891d82e089"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97411.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97411"},{"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":"b3e441c6ed8655a42e7b4da1b6dc7939f259d9c9"},{"fixed":"f6c1aad9b35fa083f48ce0c5926204891d82e089"},{"fixed":"c4cb9a728df66c46067b26263f5beb633aae4087"},{"fixed":"7c5d41f87f079990bf241359e3c1332d8d10fe87"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97411.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.24"},{"fixed":"6.12.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.53"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97411.json"}}],"schema_version":"1.9.0"}
