Detectable: no evidence on record.
No public nuclei template indexed

No public exploit code indexed in Metasploit or Exploit-DB

No attack traffic recorded by OffSeq Mirage sensors

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

An official fix has been applied to the Linux kernel to address this issue. Users should update to the fixed kernel version containing this patch to resolve the runtime PM reference leak. No additional mitigation steps are indicated.

Description

A vulnerability in the Linux kernel's gpio: arizona driver was fixed to address a runtime power management (PM) reference leak. The issue occurred when switching a persistent GPIO line from input to output; if an internal update operation failed, the acquired runtime PM reference was not released, potentially causing resource leaks.
