CVE-2026-63935

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