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 acquire queue buffers in the set_queue_properties_from_criu() function. Users should update to a kernel version that includes the commit 88ed96abbbe27b70193544fbc1ee06448c274714 or later to remediate this issue. No additional mitigation steps are specified.

Description

A vulnerability in the Linux kernel's drm/amdkfd component related to CRIU restore was resolved. The issue involved missing a call to properly acquire queue buffers in the set_queue_properties_from_criu() function, leading to uninitialized buffer fields in queue_properties. This could cause problems when subsequent code expects these buffer fields to be non-null. The fix added the missing call and corrected type casts.
