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 to call drm_gem_object_release() before freeing the GEM object on error paths in virtio_gpu_vram_create(). Users should update to the fixed kernel version once available. Since this is a kernel-level issue, applying the official kernel patch or upgrading to a patched kernel release is the recommended remediation.

Description

A use-after-free vulnerability in the Linux kernel's drm/virtio component was resolved by ensuring proper release of GEM objects on errors in virtio_gpu_vram_create(). The flaw caused freed objects to remain referenced in an interval tree, potentially leading to invalid memory accesses and unreleased locks.
