If you have these files you could skip Install HP-specific files. These files typically come preinstalled in HP Windows PCs. The HP-specific files are located in /efi/EFI/HP or /efi/EFI/Hewlet-Packard. You can replace that with the mount point your system uses. This article assumes that the ESP is mounted on /efi and that the /efi/EFI directory exists. Whithin you should also find a EFI directory, e.g. On a Linux system, the ESP is typically mounted on /boot/efi or /efi.

To update the BIOS/UEFI firmware requires HP-specific files in the EFI System Partition, also referred to as ESP. You'll also want to install some of the best Windows antivirus software to prevent first-stage infections that could lead to exploitation of these HP flaws.Instructions to Update the BIOS/UEFI for an HP Laptop on Linux Better to take pre-emptive action and make sure it can't happen by installing the above updates. In other words, you may never know whether a bad actor has infected your system firmware.

'The active exploitation of all the discovered vulnerabilities can't be detected by firmware integrity monitoring systems due to limitations of the Trusted Platform Module (TPM) measurement,' said the blog post, which further explained that Microsoft's Secure Boot process could also be bypassed. UEFI generally counters this with firmware-integrity checks during the boot-up sequence, but Binarly said that integrity checks wouldn't work in these cases. It's the software that responds when you press the power button, turning on the motherboard and activating the hard disk so that Windows, Linux or another operating system can load.īecause UEFI and BIOS operate 'below' the primary operating system, antivirus software often can't detect malware infections or other problems with them. UEFI is the successor to the better-known BIOS system, but both function the same way.

The flaws reside in the UEFI firmware that controls HP motherboards, the most basic form of software running computers. HP has further BIOS-update instructions here (opens in new tab). From there, the support site will walk you through the download-and-installation process. Once there, either type in your device's serial number or let the HP support website detect your model.
