deepin 25.1 Image Officially Released: AI-Powered, Silky Smooth Experience
In April, deepin welcomed a major version update – the official release of the deepin 25.1 image. This version accumulates results from multiple internal testing rounds, delivering comprehensive upgrades in AI capabilities, kernel performance, and desktop experience:

  • Major Evolution of UOS AI
    The writing agent has been completely restructured, supporting "outline-first" mode and multi‑format export. The system‑level Claw mode is now available, allowing the AI to automatically control the computer and execute cross‑application tasks via natural language commands. Native integration with Feishu, DingTalk, QQ and other IMs means that after authorization, the AI can collect information and generate document summaries on your behalf. The Skill Center is open and compatible with the OpenClaw ecosystem.

  • Kernel Upgraded to 6.18
    The kernel leaps from version 6.12 to 6.18, introducing a new memory allocation mechanism and the BORE scheduler, significantly improving desktop and gaming smoothness. File system read/write speeds are greatly increased, USB audio power‑saving features are added, and the potential of new hardware such as Intel APX is deeply unleashed.

  • File Manager & Desktop Experience Optimizations
    Support for pinned tabs, drag‑to‑zoom in image previews, and improved file grouping visuals. The taskbar supports splitting icons for multiple windows, the Control Center adds mouse pointer size adjustment, and multi‑screen and touch gestures are further refined.

Highlights of the Month: Kernel 6.18 upgrade / System‑level Claw mode / File Manager efficiency improvements

Rapid Security Response: Two High‑Risk Vulnerabilities Fixed Within 24 Hours
In April, deepin 25.1 pushed multiple security and quality updates, demonstrating extremely fast emergency response capabilities when faced with sudden high‑risk vulnerabilities:

  • April 13: Merged 17 security vulnerability fixes, covering historical legacy risks.

  • April 20: Fixed excessively long sudo response times in the terminal, and audio / touchpad anomalies on some laptops; also patched known CVEs.

  • April 23: Emergency fix for the "Pack2TheRoot" high‑risk vulnerability (CVE-2026-41651), which could allow unauthorised users to gain root privileges. The team completed monitoring, patching, testing, and distribution within 24 hours.

  • April 30: Rapid fix for the "Copy Fail" local privilege escalation vulnerability (CVE-2026-31431), which exists in the Linux kernel cryptography subsystem and could be exploited by attackers to obtain root privileges. The team completed the fix and pushed the update within 24 hours of discovery. Users on the 6.18 kernel can upgrade immediately; the fix for the 6.6 kernel version is complete and will be pushed later.

These two rapid responses to high‑risk vulnerabilities fully demonstrate deepin’s strong commitment to user system security.

Security Highlights: Pack2TheRoot & Copy Fail – both fixed within 24 hours / Multiple regular CVE fixes

deepin 25 WSL Offline Installation Support: Seamless Linux Experience on Windows
To meet the needs of Windows users who want to use deepin conveniently, the community officially introduces the deepin 25 WSL version, which supports completely offline installation:

  • Installation Method: Users only need to download the .wsl installation package and double‑click to complete the quick installation and deployment – no network connection is required, greatly lowering the entry barrier.

  • Environment Compatibility: Supports Windows 10/11, provides both AMD64 and ARM64 architectures. Users who already have deepin 23 WSL installed can run it side‑by‑side.

  • Community Contribution: Special thanks to community user @KuongLienHua for providing WSL image technical support.

Deepin Home & Forum
In April, a total of 173 user bug reports and feature requests were received through channels such as Deepin Home and the Forum, including:

  • Bug Reports: 143 total; 12 resolved, 38 replied to, 63 pending.

  • Feature Requests: 30 total; 4 included in version planning, 16 added to the requirements pool, 4 rejected.

III. Community SIG

deepin-kernel SIG:

  • Updated the 6.6 and 6.18 kernel branches to the latest minor versions (6.6.135 and 6.18.25), merging over 2100 patches, and synchronously fixed the core security vulnerability Copy Fail (CVE-2026-31431).

  • Updated the BORE scheduler patch to version 6.6.3 in the 6.18 kernel branch, solving smoothness issues for interactive applications under high load. Enabled support for multiple zram compression formats. Enabled dmabuf heap to support user‑space camera drivers (also synchronised to the 6.6 branch).

  • Architecture & Hardware Support Expansion: Added support for Guangrongtong network cards and the yogafan fan monitoring driver in both 6.6 and 6.18 branches. The 6.18 branch added pantherlake idle driver support, ARM64 end‑to‑end NVMe CRC acceleration, RISC-V string API acceleration, and support for printing AMD AGESA BIOS firmware version numbers.

  • Domestic Platform Adaptation & Optimisation: For LoongArch platforms, fixed DMA errors on discrete graphics cards on the 3A6000 platform, restricted a specific touchpad driver to build only on that platform, and added support for the appcompat driver compatibility module. Updated Hygon embedded model 18h patches. Merged peripheral fix patches for chips from CIX and Phytium (codec I2S, etc.).

deepin-sysdev-team:
This month, a total of 210 PRs were processed and merged, focusing on foundational environment upgrades and system hardening:

  • Security Vulnerability Fixes: Completed 27 CVE security fixes, including CopyFail (CVE-2026-31431), Pack2TheRoot (CVE-2026-41651), OpenSSL cryptographic library patch updates, and vulnerability fixes for critical network services such as nginx, curl, and openssh.

  • Package Updates: Completed 89 system package upgrades, covering development toolchains (GCC-12 general sync update, Binutils architecture integration), system‑level libraries (GLIBC, Zlib), and frequently used application components (Python 3.12.13, Vim, Ansible, Wireshark, etc.).

  • System Defect Handling: Completed 45 bug fixes, including system service‑level fixes such as systemd NSS load order and PolicyKit authentication recovery, thoroughly resolving some parallel build race conditions, and fine‑tuning the volume algorithm in the sound system. Additionally added enhanced support such as GVFS SFTP file/directory monitoring.

DDE SIG:

  • Taskbar:

    • Fixed visual anomalies such as inaccurate application active state indicators, tray icons not being centered, and icon size not resetting after the activation animation.
