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 that reorders the device removal process to unregister the bus notifier before client teardown and cancels queued work items to prevent use-after-free conditions. Users should update to a kernel version that includes this patch once available. Patch status is not explicitly confirmed in the provided data; check the vendor advisory for current remediation guidance.

Description

A use-after-free vulnerability in the Linux kernel's drm/xe/i2c driver was resolved. The issue occurs because a work item related to the i2c client device can remain queued or running after the adapter is unregistered and its memory freed, leading to dereferencing freed memory. The fix involves reordering the teardown process to unregister the bus notifier before client device teardown and canceling the work to prevent new scheduling and drain queued work items.
