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 address this issue by properly releasing the runtime PM reference on error paths. Users should update to the patched kernel version containing the commit ec30a576c2d4c0364549e6c04218f50704ef56c8 or later. No additional mitigation is required beyond applying the official fix.

Description

A vulnerability in the Linux kernel's amdgpu driver caused a runtime power management (PM) reference leak in the function amdgpu_debugfs_test_ib_show(). This leak occurs when the function's attempt to acquire a reset domain semaphore is interrupted, leading to the GPU remaining awake unnecessarily. The issue has been fixed by ensuring the runtime PM reference is properly dropped on error paths.
