{"id":"AZL-103652","summary":"CVE-2026-97411 affecting package kernel 6.6.157.1-1","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":"2026-09-25T14:16:24.791596297Z","published":"2026-09-24T17:17:18Z","upstream":["CVE-2026-97411"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97411"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-103652.json"}}],"schema_version":"1.9.0"}
