CVE-2026-63935 · Publicado 2026-07-19 · Atualizado 2026-07-19

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.
