In the Linux kernel, the following vulnerability has been resolved:Bluetooth: MGMT: Fix possible crash on mgmt_index_removedIf mgmt_index_removed is called while there are commands queued oncmd_sync it could lead to crashes like the bellow trace:0x0000053D: __list_del_entry_valid_or_report+0x98/0xdc0x0000053D: mgmt_pending_remove+0x18/0x58 [bluetooth]0x0000053E: mgmt_remove_adv_monitor_complete+0x80/0x108 [bluetooth]0x0000053E: hci_cmd_sync_work+0xbc/0x164 [bluetooth]So while handling mgmt_index_removed this attempts to dequeuecommands passed as user_data to cmd_sync.
