{"id":"AZL-88460","summary":"CVE-2026-46069 affecting package kernel for versions less than 6.6.141.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mwifiex: fix use-after-free in mwifiex_adapter_cleanup()\n\nThe mwifiex_adapter_cleanup() function uses timer_delete()\n(non-synchronous) for the wakeup_timer before the adapter structure is\nfreed. This is incorrect because timer_delete() does not wait for any\nrunning timer callback to complete.\n\nIf the wakeup_timer callback (wakeup_timer_fn) is executing when\nmwifiex_adapter_cleanup() is called, the callback will continue to\naccess adapter fields (adapter-\u003ehw_status, adapter-\u003eif_ops.card_reset,\netc.) which may be freed by mwifiex_free_adapter() called later in the\nmwifiex_remove_card() path.\n\nUse timer_delete_sync() instead to ensure any running timer callback has\ncompleted before returning.","modified":"2026-08-28T17:48:05.384912680Z","published":"2026-05-27T14:17:28Z","upstream":["CVE-2026-46069"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46069"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.141.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-88460.json"}}],"schema_version":"1.9.0"}
