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

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.

Description

In the Linux kernel, the following vulnerability has been resolved: gpio: mvebu: free generic chips on unbind irq_alloc_domain_generic_chips() allocates generic chip data that must be freed via irq_domain_remove_generic_chips(). The devres action mvebu_gpio_remove_irq_domain() only called irq_domain_remove(), which only frees the generic chips if IRQ_DOMAIN_FLAG_DESTROY_GC is set. Call irq_domain_remove_generic_chips() explicitly before irq_domain_remove() instead.
