A high-severity weakness exist in HP OMEN driver software that can be installed from Microsoft store, which affects millions of gaming laptops worldwide and leaves them vulnerable to attacks.

Tracked as CVE-2021-3437 with a CVSS score: 7.8. Threat actors may escalate privileges to kernel mode without having administrator rights, enabling them to deactivate security products, overwrite system components, and even damage the operating system.

The complete list of vulnerable devices includes HP ENVY, HP Pavilion, OMEN desktop gaming systems, and OMEN and HP Pavilion gaming laptops.

The problem is that HP OMEN Command Center includes a driver that, while ostensibly developed by HP, is actually a partial copy of another driver full of known vulnerabilities. An attacker with access to an organization’s network may also gain access to execute code on unpatched systems and use these vulnerabilities to gain local elevation of privileges. Attackers can then leverage other techniques to pivot to the broader network, like lateral movement.

HpPortIox64.sys is the driver in issue, and it gets its functionality from OpenLibSys-developed-WinRing0.sys, which was the origin of a local privilege escalation flaw in EVGA Precision X1 software last year (CVE-2020-14979, CVSS score: 7.8).

This is the second time WinRing0.sys has been identified as a source of security vulnerabilities in HP products.

A patch had been released by HP to address the vulnerability.
