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

iio: adc: ti-ads1119: fix PM reference leak in buffer preenable

ads1119 triggered buffer preenable() resumes the device with pm runtime resume and get() before starting a conversion.

If i2c smbus write byte() fails, the function returns the error directly and leaves the runtime PM usage counter elevated. The matching postdisable callback is not called when preenable fails, so the reference is leaked and the device may remain runtime-active indefinitely.

Store the I2C transfer result in ret and drop the runtime PM reference on failure before returning the error.
