Since __hid_input_report() invokes\nthe driver's raw_event callback before hid_report_raw_event()\nperforms its own report-size validation, a device sending a\ntruncated HID report can cause out-of-bounds heap reads.\n\nAdditionally, even with a full-sized report, a corrupted\nxfer->length field can cause memcpy to read beyond the report\nbuffer. The existing check only validates against the destination\nbuffer size, not the source data available in the report.\n\nAdd two checks: reject reports shorter than FT260_REPORT_MAX_LENGTH,\nand verify that xfer->length does not exceed the actual data\navailable in the report. Log warnings to aid debugging.\n\nCc: stable@vger.kernel.org\nSigned-off-by: Sebastian Josue Alba Vives <sebasjosue84@gmail.com>\n---\n drivers/hid/hid-ft260.c | 11 +++++++++++\n 1 file changed, 11 insertions(+)", "diff": "diff --git a/drivers/hid/hid-ft260.c b/drivers/hid/hid-ft260.c\nindex 333341e80..68008a423 100644\n--- a/drivers/hid/hid-ft260.c\n+++ b/drivers/hid/hid-ft260.c\n@@ -1068,6 +1068,17 @@ static int ft260_raw_event(struct hid_device *hdev, struct hid_report *report,\n \tstruct ft260_device *dev = hid_get_drvdata(hdev);\n \tstruct ft260_i2c_input_report *xfer = (void *)data;\n \n+\tif (size < FT260_REPORT_MAX_LENGTH) {\n+\t\thid_warn(hdev, \"short report: %d\\n\", size);\n+\t\treturn 0;\n+\t}\n+\n+\tif (xfer->length > size - offsetof(struct ft260_i2c_input_report, data)) {\n+\t\thid_warn(hdev, \"payload %d exceeds report size %d\\n\",\n+\t\t\t xfer->length, size);\n+\t\treturn 0;\n+\t}\n+\n \tif (xfer->report >= FT260_I2C_REPORT_MIN &&\n \t xfer->report <= FT260_I2C_REPORT_MAX) {\n \t\tft260_dbg(\"i2c resp: rep %#02x len %d\\n\", xfer->report,\n", "prefixes": [ "v2" ] }
