In the Linux kernel, the following vulnerability has been resolved:

hwmon: (tps53679) Fix array access with zero-length block read

i2c_smbus_read_block_data() can return 0, indicating a zero-length read. When this happens, tps53679_identify_chip() accesses buf[ret - 1] which is buf[-1], reading one byte before the buffer on the stack.

Fix by changing the check from "ret < 0" to "ret <= 0", treating a zero-length read as an error (-EIO), which prevents the out-of-bounds array access.

Also fix a typo in the adjacent comment: "if present" instead of duplicate "if".
