CVE-2024-47663 Information
Share on:Description
In the Linux kernel the following vulnerability has been resolved:
staging: iio: frequency: ad9834: Validate frequency parameter value
In ad9834_write_frequency() clk_get_rate() can return 0. In such case ad9834_calc_freqreg() call will lead to division by zero. Checking ‘if (fout > (clk_freq / 2))’ doesn’t protect in case of ‘fout’ is 0. ad9834_write_frequency() is called from ad9834_write() where fout is taken from text buffer which can contain any value.
Modify parameters checking.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
