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

This vulnerability has been resolved in the Linux kernel by correcting the reference handling in virtio_gpu_resource_create_blob_ioctl(). Users should apply the official kernel updates that include this fix. Patch status is not explicitly stated in the provided data; therefore, check the vendor advisory for current remediation guidance.

Description

A vulnerability in the Linux kernel's drm/virtio component caused object leaks in the virtio_gpu_resource_create_blob_ioctl() function due to improper reference handling. The function incorrectly calls drm_gem_object_release() on error paths instead of drm_gem_object_put(), preventing the free callback from running and leading to resource leaks. This issue has been resolved by correcting the reference drop method.
