"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: MGMT: Fix status of pending commands flushed on power off\n\ncmd_complete_rsp() receives a struct cmd_lookup and, for a pending\ncommand that has no cmd_complete callback, falls through to\ncmd_status_rsp(cmd, data). cmd_status_rsp() reads data as a u8 *, so\nthe status sent comes from the first byte of match->sk's\nrepresentation, not from match->mgmt_status.\n\ncommit f53e1c9c726d (\"Bluetooth: MGMT: Fix possible crash on\nmgmt_index_removed\") changed the callers' data from &status to &match\nand updated the cmd_complete branch to match->mgmt_status, but left\nthe fall-through passing data unchanged.\n\nIn mgmt_index_removed() match->sk is NULL, so every such command is\nanswered with status 0x00 (Success) instead of\nMGMT_STATUS_INVALID_INDEX. In __mgmt_power_off() it is NULL too,\nunless a Set Powered command was pending: then settings_rsp() has\nstored that command's socket in match->sk, and the byte sent comes\nfrom the socket pointer. Either way the status the caller set,\nMGMT_STATUS_NOT_POWERED (or MGMT_STATUS_INVALID_INDEX when the device\nis being unregistered), is lost.\n\nPass the status the callers set.\n\nThis was seen on a QCA9377 laptop: bluetoothd's Start Discovery,\npending when the adapter was powered off, was answered with Command\nStatus 0x00 and no parameters, and bluetoothd 5.72 crashed on the\nzero-length success. BlueZ master has since added the length check\non that path (\"adapter: Fix crash on short start discovery reply\",\nBlueZ a734b06059cb), but userspace should still be told Not Powered,\nnot Success.\n\nTested on Ubuntu 7.0.0-31 with a virtual controller (hci_vhci):\npower off is held in HCI Write Scan Enable while a Start Discovery is\nsubmitted, and the flush answers it with status 0x00 before this\nchange and 0x0f (Not Powered) after."
