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 fixed in several Linux kernel commits as listed in the established facts. Users should update their Linux kernel to a version including these fixes. No additional mitigation is required once the system is updated.

Description

A vulnerability in the Linux kernel's AMD GPU driver (drm/amd/pm/si) was fixed to prevent scheduling thermal work when the thermal work queue is not initialized. This issue occurs when Dynamic Power Management (DPM) is disabled using the amdgpu.dpm=0 module parameter, which leaves the thermal work queue uninitialized. Scheduling work on an uninitialized queue could lead to kernel instability or crashes.

Impact

If exploited or triggered, this flaw could cause kernel instability or crashes due to scheduling work on an uninitialized queue. This may affect system reliability on systems running the affected Linux kernel version with AMD GPUs and DPM disabled.

Summary

The Linux kernel contained a flaw in the AMD GPU driver's power management code where thermal work could be scheduled even if the thermal work queue was not initialized. This situation arises when DPM is disabled via the amdgpu.dpm=0 parameter. The fix ensures that no thermal work is scheduled unless the queue is properly initialized, preventing potential kernel faults related to improper work scheduling.
