Title
iio: chemical: scd30: fix division by zero in write_raw
Summary
In the Linux kernel, the following vulnerability has been resolved: iio: chemical: scd30: fix division by zero in write_raw Add a zero check for val2 before using it as a divisor when setting the sampling frequency. A user writing a zero fractional part to the sampling_frequency sysfs attribute triggers a division by zero in the kernel.
Severity
