  "details": "In the Linux kernel, the following vulnerability has been resolved:  Bluetooth: bpa10x: avoid OOB read of revision string in bpa10x_setup()  bpa10x_setup() sends the vendor command 0xfc0e and passes the response to bt_dev_info() and hci_set_fw_info() as a \"%s\" string starting at skb-\u003edata + 1, without checking the length:  \tbt_dev_info(hdev, \"%s\", (char *)(skb-\u003edata + 1)); \thci_set_fw_info(hdev, \"%s\", skb-\u003edata + 1);  A device that returns a one-byte response (status only) leaves skb-\u003edata + 1 past the end of the data, and the %s walk reads adjacent slab memory until it meets a NUL. The same happens when the payload is not NUL-terminated within skb-\u003elen. The out-of-bounds bytes end up in the kernel log and the firmware-info debugfs file.  Print the revision string with a bounded \"%.*s\" limited to skb-\u003elen - 1 instead. This keeps the string readable for well-behaved devices while never reading past the received data, and does not fail setup, so a device returning a short or unterminated response keeps working.",
