NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt-debug-modules package and not the kernel-rt-debug-modules package as distributed by RHEL.
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.
