CVE-2024-50233

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

staging: iio: frequency: ad9832: fix division by zero in ad9832calcfreqreg()

In the ad9832writefrequency() function, clkgetrate() might return 0. This can lead to a division by zero when calling ad9832calcfreqreg(). The check if (fout > (clkgetrate(st->mclk) / 2)) does not protect against the case when fout is 0. The ad9832writefrequency() function is called from ad9832_write(), and fout is derived from a text buffer, which can contain any value.
