Millions of HP OMEN laptop and desktop gaming computers are exposed to attacks by a high severity vulnerability that can let threat actors trigger denial of service states or escalate privileges and disable security solutions.

The security flaw (tracked as CVE-2021-3437) was found in a driver used by the OMEN Gaming Hub software that comes pre-installed on all HP OMEN desktops and laptops.

CVE-2021-3437 is caused by HP's choice to use vulnerable code partially copied from WinRing0.sys, an open source driver, to build the HpPortIox64.sys driver the OMEN Gaming Hub software uses to read/write kernel memory, PCI configurations, IO ports, and Model-Specific Registers (MSRs).

The complete list of vulnerable devices is available here and it includes OMEN and HP Pavilion gaming laptops, as well as HP ENVY, HP Pavilion, and OMEN desktop gaming systems.

Security patches available since July

HP has released patches for this high severity vulnerability through the Microsoft Store on July 27 and has published a security advisory earlier.

SentinelOne also shared their findings in today's report to warn users to update their software and defend their systems against attackers using CVE-2021-3437 exploits.

"While we haven’t seen any indicators that these vulnerabilities have been exploited in the wild up till now, using any OMEN-branded PC with the vulnerable driver utilized by OMEN Gaming Hub makes the user potentially vulnerable," SentinelOne warned.

"Therefore, we urge users of OMEN PC’s to ensure they take appropriate mitigating measures without delay."
