CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's NXP SAR ADC driver, where improper validation of the sampling frequency value can lead to a division by zero error if a user inputs zero or a negative value. This flaw may result in kernel crashes or undefined behavior, impacting system stability. Linux system administrators and developers utilizing the NXP SAR ADC driver should prioritize applying the fix to mitigate potential disruptions.
Original NVD 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.
