CVE-2026-63935
Description
In the Linux kernel, the following vulnerability has been resolved:
iio: adc: nxp-sar-adc: fix division by zero in write_raw
Add a validation check for the sampling frequency value before using it
as a divisor. A user writing zero or a negative value to the
sampling_frequency sysfs attribute triggers a division by zero in the
kernel.
Also prevent unsigned integer underflow when the computed cycle count is
smaller than NXP_SAR_ADC_CONV_TIME, which would wrap the u32 inpsamp to
a huge value.
