CVE-2026-98672: iio: adc: stm32-adc: fix possible division by zero in processed channel
Noroxi assessment
Priority: Monitor (action score 0/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
- Fixed version: Linux Linux 30d27899cbba5b080954b5d3741bd535806c3101, 55f1cebee909c9a0d5c2e494bcfaabed54750eb5, 6dd3bf785d0307d1cf8f4a97c2240b0af14bef50; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes.
Low priority for now. Upgrade to Linux Linux 30d27899cbba5b080954b5d3741bd535806c3101, 55f1cebee909c9a0d5c2e494bcfaabed54750eb5, 6dd3bf785d0307d1cf8f4a97c2240b0af14bef50; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 Release Notes or later.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
In the Linux kernel, the following vulnerability has been resolved: iio: adc: stm32-adc: fix possible division by zero in processed channel In case the conversion has failed or returned zero, processing *val can lead to a division by zero. Need to check for errors, or converted value is zero, before processing the data. In case the converted value is zero, e.g. the Vrefint channel, this should be considered as invalid in all cases.

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
