USB: serial: io_ti: fix heap overflow in build_i2c_fw_hdr()

Description

In the Linux kernel, the following vulnerability has been resolved: USB: serial: io_ti: fix heap overflow in build_i2c_fw_hdr() build_i2c_fw_hdr() allocates a fixed-size buffer of (16*1024 - 512) + sizeof(struct ti_i2c_firmware_rec) bytes, then copies le16_to_cpu(img_header->Length) bytes into it without validating that Length fits within the available space after the firmware record header. img_header->Length is a __le16 from the firmware file and can be up to 65535. check_fw_sanity() validates the total firmware size but not img_header->Length specifically. Fix by rejecting images where img_header->Length exceeds the available destination space.
