"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: libertas: fix use-after-free in lbs_free_adapter()\n\nThe lbs_free_adapter() function uses timer_delete() (non-synchronous)\nfor both command_timer and tx_lockup_timer before the structure is\nfreed. This is incorrect because timer_delete() does not wait for\nany running timer callback to complete.\n\nIf a timer callback is executing when lbs_free_adapter() is called,\nthe callback will access freed memory since lbs_cfg_free() frees the\ncontaining structure immediately after lbs_free_adapter() returns.\n\nBoth timer callbacks (lbs_cmd_timeout_handler and lbs_tx_lockup_handler)\naccess priv->driver_lock, priv->cur_cmd, priv->dev, and other fields,\nwhich would all be use-after-free violations.\n\nUse timer_delete_sync() instead to ensure any running timer callback\nhas completed before returning.\n\nThis bug was introduced in commit 8f641d93c38a (\"libertas: detect TX\nlockups and reset hardware\") where del_timer() was used instead of\ndel_timer_sync() in the cleanup path. The command_timer has had the\nsame issue since the driver was first written."
