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

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 to track and unregister the OVL adaptor platform device properly during probe failure and normal removal. Users should apply the official Linux kernel patch that addresses this issue. Since this is a kernel-level fix, updating to a kernel version containing this patch is recommended.

Description

A vulnerability in the Linux kernel's drm/mediatek driver was fixed to address a platform device leak. The mtk_drm_probe() function creates an OVL adaptor platform device but fails to unregister it if later initialization steps fail, leading to resource leakage. The fix ensures proper tracking and unregistration of the OVL adaptor device on probe failure and during normal removal.
