Overview
CVE-2026-63935 is a known-severity vulnerability. It was published on July 19, 2026.
Technical 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.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.

How can CyberStrike help with CVE-2026-63935?
CyberStrike is an open-source, AI-augmented pentesting engine.
