On September 21, 2026, AMD posted AMDGPU kernel patches that add the GDDR7 memory identifier and new IP blocks, signalling the first RDNA5 GPUs. Linux users get the benefit of this open-source enablement months before any card ships.
On August 16, 2026, Linus Torvalds released the stable Linux 7.2 kernel after seven release candidates, bringing cache-aware scheduling, USB4STREAM host-to-host transfers, and measured gains on EXT4, XFS, and MongoDB. For administrators, this is a performance release that arrives through the standard distro kernel update — the real work is testing MySQL and MongoDB workloads before rolling it out.
On August 6, 2026, MIT CSAIL researchers unveiled at Black Hat USA a new CPU attack that bypasses Spectre v2 fixes on both Intel and AMD processors. TONTOU exploits the gap between branch predictor neutralization and its actual use, extracting `/etc/shadow` at 5.47 bytes per second with 91.97% accuracy.
Linux 7.2 Release Candidate 5 ships with over 35% of its patch volume in networking drivers — a post-conference backlog catch-up. The stable kernel is targeted for August 16, 2026. Sysadmins should schedule their validation windows now.
On August 6, 2026, a speculative execution vulnerability was publicly disclosed, affecting all AMD Zen 1 through Zen 4 processors via the Linux kernel's SRSO mitigation. A fix is already in linux.git; the community must patch without delay.
