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 is available that adds synchronization to drain queued irq_work after free_irq() calls in the gp2ap020a00f driver. Users should apply the updated Linux kernel version containing this fix. No additional mitigation is required beyond applying the official patch.

Description

A use-after-free vulnerability in the Linux kernel's iio light sensor driver (gp2ap020a00f) was resolved. The issue occurs because the threaded IRQ handler queues work that may run after free_irq() has been called, potentially accessing freed memory. The fix adds synchronization to ensure queued work is drained after free_irq(), preventing use-after-free.
