      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: btusb: clamp SCO altsetting table indices\n\nbtusb_work() maps the number of active SCO links to USB alternate\nsettings through a three-entry lookup table when CVSD traffic uses\ntransparent voice settings. The lookup currently indexes alts[] with\ndata->sco_num - 1 without first constraining sco_num to the number of\navailable table entries.\n\nWhile the table only defines alternate settings for up to three SCO\nlinks, data->sco_num comes from hci_conn_num() and is used directly.\nCap the lookup to the last table entry before indexing it so the\ndriver keeps selecting the highest supported alternate setting without\nreading past alts[].",
