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 AMD display driver to check for NULL returns from dc_state_create_copy() and abort suspend with an error if the copy fails. Users should update to the patched kernel version containing this fix. No other mitigation is indicated.

Description

A vulnerability in the Linux kernel's AMD display driver was resolved by adding a NULL check for the dc_state_create_copy() function in the dm_suspend() routine. The function dc_state_create_copy() can return NULL on allocation failure, but dm_suspend() previously did not handle this correctly, leading to a NULL pointer dereference during GPU reset recovery in dm_resume(). The fix returns an error immediately if the copy fails, preventing the NULL cached state from causing a crash.
