Old SGI Drivers Being Removed In Linux 7.3 Over Security Concerns
The Linux 7.3 kernel will be removing old SGI drivers due to security concerns. The SGI GRU driver, which is used for the Global Reference Unit hardware resource, is being removed as it poses a security risk and is no longer used by newer systems. The removal of the SGI GRU driver will also result in the removal of the SGI XP drivers, which depend on the GRU driver to function.
- ▪The SGI GRU driver is being removed from the Linux 7.3 kernel due to security concerns.
- ▪The SGI GRU driver is no longer used by systems newer than the SGI UV2 series, which was released in 2012.
- ▪The removal of the SGI GRU driver will result in the removal of 6.8k lines of code.

Old SGI Drivers Being Removed In Linux 7.3 Over Security Concerns Written by Michael Larabel in Hardware on 10 August 2026 at 05:59 AM EDT. Add A Comment On top of various other Linux drivers for old hardware being removed due to noise generated by AI/LLM coding agents, there are more examples coming with Linux 7.3 as some old Silicon Graphics (SGI) drivers are being removed from the mainline Linux kernel over security concerns. HPE engineer Dimitri Sivanich authored a patch to remove the SGI GRU driver, which is for the Global Reference Unit (GRU) hardware resource located on the system chipset for memory that can be mmap'ed from user-space. The patch simply noted that the driver has become a security concern and isn't used by anything newer than the SGI UV2 series.
