"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ntty: serial: qcom-geni-serial: fix slab-out-of-bounds on RX FIFO buffer\n\nDriver's probe allocates memory for RX FIFO (port->rx_fifo) based on\ndefault RX FIFO depth, e.g. 16. Later during serial startup the\nqcom_geni_serial_port_setup() updates the RX FIFO depth\n(port->rx_fifo_depth) to match real device capabilities, e.g. to 32.\n\nThe RX UART handle code will read \"port->rx_fifo_depth\" number of words\ninto \"port->rx_fifo\" buffer, thus exceeding the bounds. This can be\nobserved in certain configurations with Qualcomm Bluetooth HCI UART\ndevice and KASAN:\n\n Bluetooth: hci0: QCA Product ID :0x00000010\n Bluetooth: hci0: QCA SOC Version :0x400a0200\n Bluetooth: hci0: QCA ROM Version :0x00000200\n Bluetooth: hci0: QCA Patch Version:0x00000d2b\n Bluetooth: hci0: QCA controller version 0x02000200\n Bluetooth: hci0: QCA Downloading qca/htbtfw20.tlv\n bluetooth hci0: Direct firmware load for qca/htbtfw20.tlv failed with error -2\n Bluetooth: hci0: QCA Failed to request file: qca/htbtfw20.tlv (-2)\n Bluetooth: hci0: QCA Failed to download patch (-2)\n ==================================================================\n BUG: KASAN: slab-out-of-bounds in handle_rx_uart+0xa8/0x18c\n Write of size 4 at addr ffff279347d578c0 by task swapper/0/0\n\n CPU: 0 PID: 0 Comm: swapper/0 Not tainted 6.1.0-rt5-00350-gb2450b7e00be-dirty #26\n Hardware name: Qualcomm Technologies, Inc.
