# Intel VTune Profiler: out-of-bounds write in Ring 1 drivers allows local denial of service

Link for people: https://infrastack.ai/live/CVE-2026-33279 (this .md is for agents)

Intel VTune Profiler before 2026.0.0 has an out-of-bounds write in its Ring 1 device driver component. A local user with an ordinary authenticated account can crash the system with a denial of service.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed VTune Profiler version in its about dialog or with the installed package manager listing; versions before `2026.0.0` are affected.

## Fix

- Intel VTune Profiler: move to `2026.0.0` or later.

## Timeline

- 2026-11-10T17:22:42+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-33279

## From the sources

Out-of-bounds write for the Intel(R) VTune(TM) Profiler software before version 2026.0.0 within Ring 1: Device Drivers may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a low complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (low), integrity (low) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
