      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nHID: nintendo: fix out-of-bounds read in joycon_ctlr_read_handler()\n\njoycon_ctlr_read_handler() casts an incoming HID input report to\nstruct joycon_input_report and parses it, guarding the cast only with a\n12-byte length check:\n\n\tif (size >= 12) /* make sure it contains the input report */\n\t\tjoycon_parse_report(ctlr, (struct joycon_input_report *)data);\n\nstruct joycon_input_report is 49 bytes: a 13-byte header followed by a\nunion whose IMU arm is 36 bytes. For an IMU report joycon_parse_report()\n-> joycon_parse_imu_report() walks that union (struct offsets 13..48),\nso a report of exactly 12 bytes with data[0] == JC_INPUT_IMU_DATA passes\nthe guard yet is read up to 37 bytes past its declared length. The\nover-read bytes are decoded into accelerometer/gyroscope values and\nforwarded to userspace through the \"(IMU)\" input device, leaking\ndriver-internal memory. data[0] and size are fully controlled by a\nmalicious or spoofed Joy-Con/Pro Controller.\n\nReceive buffers are sized to the maximum report length, so this is an\nover-read within the allocation rather than a slab OOB, but the decoded\nbytes still reach userspace.\n\nThe sibling subcmd path in joycon_ctlr_handle_event() already bounds the\nsame cast correctly:\n\n\tif (size < sizeof(struct joycon_input_report) ||\n\t    data[0] != JC_INPUT_SUBCMD_REPLY)\n\t\tbreak;\n\nUse the same sizeof(struct joycon_input_report) bound here.",
