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 applied to the Linux kernel to properly balance the runtime PM reference in nouveau_connector_detect(). Users should update to the fixed kernel version when available. Patch status is not explicitly stated in the provided data; check the vendor or Linux kernel advisories for the exact fixed versions and update accordingly.

Description

A vulnerability in the Linux kernel's drm/nouveau driver caused a runtime power management (PM) reference leak in the nouveau_connector_detect() function. If the function nvif_outp_edid_get() fails, nouveau_connector_detect() would return early without releasing the runtime PM reference, causing the device to remain powered on unnecessarily until the next successful detection. This issue has been fixed by ensuring the runtime PM reference is properly balanced on all error paths.
