In Nvidia GPU Display-Treibern für Linux existieren mehrere Schwachstellen. Unsachgemäßer Umgang mit Berechtigungen oder Privilegien im Kerneltreiber ist die Ursache. Ein lokaler Angreifer kann diese Schwachstellen ausnutzen, um einen Denial of Service zu verursachen.
Es existiert eine Schwachstelle im Nvidia GPU Display Treiber für Windows. Im Kernel-Modus-Schicht-Handler (nvlddmkm.sys) für private IOCTLs besteht eine NULL-Zeiger-Dereferenz. Ein lokaler Angreifer kann diese Schwachstelle ausnutzen, um einen Denial of Service zu verursachen.

Es existiert eine Schwachstelle in der NVIDIA vGPU Software im Virtual GPU Manager (nvidia.ko). Ein Angreifer im Gastbetriebssystem kann diese Schwachstelle ausnutzen, um einen GPU-Interrupt-Sturm auf dem Hypervisor-Host auszulösen, was zu einem Denial-of-Service führt.

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
