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 and has been applied in the Linux kernel source code revisions identified by commits 780ad8e4df9f767806587d33b42372acf8fbe5e6, 87c2f8ce1100ccbbc40bfab067741edbd1f0ef02, 59aa1f8c95941e623891d46c805e8fb1257b5a3d, and 1e04611d3735543bd80a67d9d13dc13f503746fb. Users and maintainers should update to a fixed kernel version containing these commits to remediate the issue.

Description

A runtime power management (PM) reference leak was fixed in the Linux kernel's nouveau driver in the function nouveau_connector_detect(). If the function nvif_outp_edid_get() fails, the runtime PM reference was not properly released, causing the device to remain powered on unnecessarily until the next successful detection. This issue has been corrected by balancing the runtime PM references on all exit paths.

Impact

The impact is limited to a runtime power management leak that causes the device to remain powered on unnecessarily, potentially leading to increased power consumption. There is no indication of security compromise, data loss, or system instability beyond this power management issue.

Summary

The vulnerability in the Linux kernel's nouveau DRM driver involved a runtime PM reference leak in the nouveau_connector_detect() function. Specifically, when nvif_outp_edid_get() fails, the function returned early without dropping the runtime PM reference acquired at the start, resulting in the device staying powered on longer than intended. The fix ensures that the runtime PM reference is properly released on all error paths, preventing the leak.
