The Linux 7.3 kernel has been officially released, focusing on improved I/O performance and expanded support for the AMD Zen 6 architecture. The update introduces a driver for the Steam Controller 2026 and includes optimizations for legacy AMD GPU hardware.

Developers have enhanced VRAM management for systems with limited video memory. The release also incorporates various bug fixes addressed over the past week, specifically targeting issues related to AI and LLM workloads.

Key stability improvements include patches for rare SMP boot failures identified prior to 2024. Additionally, the kernel now provides specific workarounds for Samsung 990 PRO and 990 EVO Plus SSD models when used with certain firmware versions.
