In a recent security advisory, HP has announced the discovery of a critical vulnerability in its HP Support Assistant software, which is used on a wide range of HP laptops and desktops. The flaw could potentially allow attackers to gain elevated privileges on affected systems, posing a serious risk to users’ data and device security.
The vulnerability, tracked as CVE-2025-43026 with a high severity score, and affecting versions of HP Support Assistant earlier than 9.44.18.0, could allow a local attacker (someone who already has access to your device) to escalate their privileges. This means they could gain more control over the system than they’re supposed to, which might lead to data theft, system malfunctions, or even a complete denial of service (DoS), making your device inoperable.
The root cause of the vulnerability is linked to something known as an “arbitrary file write” issue. This flaw allows an attacker to manipulate system files that should be protected, potentially giving the ability to make dangerous changes to your system. While it requires local access to the machine (meaning the attacker needs to be physically present or have access to an already-compromised user account), the potential for harm is high, which is why HP is urging users to update their software immediately.
Which Devices Are Affected?
The vulnerability impacts HP Support Assistant across multiple HP devices running versions earlier than 9.44.18.0. This is not limited to any one specific model, so if you’re using an HP laptop or desktop, it’s a good idea to check whether your system is affected.
HP has rolled out a patch to address the vulnerability, and they strongly recommend updating to HP Support Assistant version 9.45.11.0 or later. The new version resolves the security risk and helps ensure your device remains safe from potential exploits.
You can check the version:
- Through the application’s gear/settings icon >> clicking “About HP Support Assistant”
- through the “Control Panel/Add or remove programs settings page
- or through Start >> searching >> right-click (or choosing from the right) then click “App settings.”
If you’re using HP devices, make sure to update your software to stay protected. You can download the latest update for your system from HP’s official support page here.
Even though this issue requires local access, it’s still crucial to act quickly to update your software. If you’re not on the latest version, you could be leaving your system vulnerable to attackers who might gain unauthorized access or cause damage to your device. Check for updates and update HP Support Assistant to the latest version, currently 9.45.11.0.
