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 for this vulnerability has been implemented in the Linux kernel by correcting the resource release logic in virtio_gpu_resource_create_ioctl(). Users should apply the official kernel updates that include this fix. Since this is a resource leak, no additional mitigation steps beyond applying the patch are necessary.

Description

A vulnerability in the Linux kernel's drm/virtio component caused an object leak in the function virtio_gpu_resource_create_ioctl(). The issue arises because drm_gem_object_release() is called incorrectly on an error path, preventing the proper freeing of resources. This leads to leaks of virtio_gpu_object, its pages, scatter-gather table, resource ID, and host-side resource. The fix involves using drm_gem_object_put() to correctly drop the reference and free the object.
