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 in the Linux kernel by adding SEC2 to the GA100 chip table, resolving the NULL pointer dereference and preventing the crash. Users should update to the fixed kernel version containing this patch. Patch status is confirmed by the vendor advisory describing the fix.

Description

A vulnerability in the Linux kernel's drm/nouveau/gsp component related to the SEC2 falcon on GA100 chip tables has been resolved. The issue involved a NULL pointer dereference during the GSP-RM boot process caused by missing .sec2 entries, leading to a crash. This was fixed by adding SEC2 to the GA100 chip table to ensure proper device->sec2 access during booter initialization.
