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

The vulnerability is fixed in the Linux kernel by commits fafefa925ed7ec10383d9bf0378abf878b7f13cb, f73b94acc7ec81f9c49feb87f649ba5a80a0905c, and d338af069f08658f53231adb445ddb10048730ac. Users should update to a Linux kernel version that includes these fixes. No additional mitigation steps are indicated.

Description

A vulnerability in the Linux kernel's ADE9000 ADC driver caused Phase C dip events to be unreported due to an incorrect upper bound in scanning event bits. This issue was fixed by increasing the scanning range to include the missing event bit, ensuring proper handling of Phase C dip events.

Impact

Phase C dip events were never reported by the ADE9000 ADC driver due to the scanning boundary error. This could lead to incomplete or inaccurate event reporting in systems relying on this driver for power monitoring or related functions. There is no indication of active exploitation or broader system compromise from this issue.

Summary

The Linux kernel ADE9000 ADC driver did not handle Phase C dip events correctly because the scanning of STATUS1 event bits excluded the highest event bit (bit 25, ADE9000_ST1_DIPC_BIT). The exclusive upper bound for scanning was set to 25, which omitted this bit. The fix involved increasing the scanning upper bound to 26, allowing the driver to detect and report Phase C dip events properly. This vulnerability affects Linux kernel version 6.18 and was resolved in specific commits identified by their hashes.
