Description OSIDB Bzimport 2024-07-29 17:20:40 UTC 
In the Linux kernel, the following vulnerability has been resolved:

iio: chemical: bme680: Fix overflows in compensate() functions

There are cases in the compensate functions of the driver that
there could be overflows of variables due to bit shifting ops.
These implications were initially discussed here [1] and they
were mentioned in log message of Commit 1b3bd8592780 ("iio:
chemical: Add support for Bosch BME680 sensor").
