  "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.",
