Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A Improper Authentication vulnerability in TLP allows local users to arbitrarily control the power profile in use as well as the daemon’s log settings.This issue affects TLP: from 1.9 before 1.9.1.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

TLP versions 1.9 before 1.9.1 contain an improper authentication vulnerability allowing local users to bypass authentication controls and arbitrarily manipulate power profiles and the daemon's log settings. This is a local privilege escalation issue where the daemon does not properly validate user identity before accepting configuration changes.

MitigationUpgrade TLP to version 1.9.1 or later to obtain the authentication fix. Verify that power management functionality operates normally after the upgrade.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify TLP is installed
    Run 'tlp --version' or check package manager: 'dpkg -l | grep tlp' (Debian) or 'rpm -q tlp' (RHEL)
    Affected if TLP is not installed, this CVE does not apply
  2. Determine installed TLP version
    Execute 'tlp --version' and note the output (e.g., 1.9.0, 1.9, 1.9.1, etc.)
    Affected if Version is 1.9 or 1.9.0 (any 1.9.x before 1.9.1)
  3. Confirm TLP daemon is running
    Run 'systemctl status tlp' or 'ps aux | grep tlp'
    Affected if Daemon is active and version is in the affected range (1.9.x before 1.9.1)
  4. Check if any power profile configuration files exist
    Inspect /etc/tlp.d/ or ~/.config/tlp/ directories for configuration files that could be manipulated
    Affected if Config files exist and TLP daemon is running an affected version

A user is affected if TLP version 1.9 or 1.9.0 is installed and the TLP daemon is running, allowing local users to bypass authentication and modify power profiles or log settings.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade TLP to version 1.9.1 or later to obtain the authentication fix. Verify that power management functionality operates normally after the upgrade.

Recommended fix High confidence

TLP 1.9.1

  1. Check current TLP version with: tlp-stat -s or dpkg -l | grep tlp (Debian/Ubuntu) / rpm -qi tlp (RHEL/Fedora)
  2. Update your package repository: sudo zypper refresh (openSUSE/SUSE) or sudo apt update (Debian/Ubuntu)
  3. Upgrade TLP to version 1.9.1: sudo zypper in tlp=1.9.1 (openSUSE/SUSE) or sudo apt install tlp=1.9.1 (Debian/Ubuntu)
  4. If using a source-based install, download TLP 1.9.1 from https://github.com/linrunner/TLP/releases
  5. Restart the TLP service: sudo tlp start
  6. Verify the new version is installed: tlp-stat -s
