The security error (detected as CVE-2021-3437) was detected in a driver used by the OMEN Gaming Hub software that is preinstalled on all HP OMEN desktops and laptops.

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

The full list of vulnerable devices is available here and includes OMEN and HP Pavilion gaming laptops, as well as HP ENVY, HP Pavilion and OMEN gaming desktops.
