Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> staging: iio: frequency: ad9834: Validate frequency parameter value<br /> <br /> In ad9834_write_frequency() clk_get_rate() can return 0. In such case<br /> ad9834_calc_freqreg() call will lead to division by zero. Checking<br /> &amp;#39;if (fout &gt; (clk_freq / 2))&amp;#39; doesn&amp;#39;t protect in case of &amp;#39;fout&amp;#39; is 0.<br /> ad9834_write_frequency() is called from ad9834_write(), where fout is<br /> taken from text buffer, which can contain any value.<br /> <br /> Modify parameters checking.<br /> <br /> Found by Linux Verification Center (linuxtesting.org) with SVACE.
