A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

A fix has been implemented in the Linux kernel to address this issue by adding proper checks for zero or failed ADC conversion values before processing. Users should update to the fixed kernel version once available. Since this is a kernel-level fix, upgrading the kernel is the recommended remediation.

Description

A vulnerability in the Linux kernel's stm32-adc driver could cause a division by zero error when processing ADC channel data if the conversion fails or returns zero. This occurs because the code does not properly check for error conditions or zero values before performing division. The issue has been fixed by adding checks to treat zero or failed conversions as invalid data.
