staging: iio: frequency: ad9834: Validate frequency parameter value

State: Published
Severity: Not scored
Published: Oct 9, 2024
Updated: May 11, 2026
Reserved: Sep 30, 2024

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.
