Since Linux 5.18 there has been Indirect Branch Tracking (IBT) in the mainline kernel that was contributed by Intel as part of their Control-flow Enforcement Technology (CET). For Linux 6.4 Intel engineers tried to get the Shadow Stack support mainlined as the other part of CET, but issues were uncovered at the last minute. Hopefully Shadow Stack support will be merged for the v6.5 cycle but beyond that host support, Intel engineers have also been working on CET virtualization for enabling these security features for use within virtual machines...

Last week Corsair announced the MP700 series as their first PCIe 5.0 NVMe solid-state drives. While the performance is quite speedy for sequential reads and writes, in practice this drive struggled under Linux with real-world workloads. When not adding an after-market heatsink, the MP700 was quick to exhibit EXT4 file-system errors.

Intel today published 38 new security advisories in their first Patch Tuesday roundabout since February. Among the new disclosures today are CVE-2023-28410 as an i915 Linux kernel graphics driver vulnerability that could lead to local privilege escalation...

While Intel's in-development Xe kernel graphics driver is focused on supporting Tigerlake/Gen12 graphics and newer integrated/discrete graphics with this modern open-source driver with many design improvements over the aging i915 kernel driver, there looks to be one feature that as currently positioned will be missing for DG2/Alchemist: HuC support for helping with media offloading...
