macOS kernel TCP stack has an overflow vulnerability
A blog post published by Photon on April 6 revealed a TCP stack vulnerability in macOS that can lead to network failure. The issue is triggered by a 32-bit counter in the Apple XNU kernel. When the system uptime reaches 49 days, 17 hours, 2 minutes, and 47 seconds, the internal TCP timer stops functioning. As a result, TCP connections in certain states cannot be properly recycled, eventually exhausting ephemeral ports and preventing the system from establishing any new TCP connections. Only certain types of connections, such as ICMP, remain unaffected.
Photon’s testing confirms that this kernel flaw affects at least macOS Catalina 10.15 and later versions, while it is unclear whether earlier versions are impacted. Notably, this issue does not cause kernel crashes or generate obvious error logs, making it a silent failure that is difficult for users to diagnose in a timely manner.
Interestingly, due to macOS’s system update cycle, Apple typically pushes updates and triggers restarts within the window before the bug occurs. As a result, only devices that run continuously for extended periods without restarting are likely to be affected. Source
Google Pixel 10a launches in Japan with an exclusive variant
On April 7, Google announced that the Pixel 10a has officially opened for pre-orders in Japan. The company also partnered with local creative agency HERALBONY to introduce a Japan-exclusive color variant, “Isai Blue.”

It comes bundled with an exclusive protective case and stickers, and features custom wallpapers designed by HERALBONY artists, along with a system-wide theme package in a unified color style.
In addition to the limited-edition color, other color options are also available simultaneously. The Google Pixel 10a starts at JPY 79,900 in the Japanese market, with the new “Isai Blue” limited edition set to begin shipping on May 20. Source

Anthropic and others launch Project Glasswing cybersecurity initiative
On April 7, Anthropic, together with 11 companies including Amazon, Apple, Google, Microsoft, and NVIDIA, launched the Project Glasswing cybersecurity initiative. The project aims to mitigate the risks of AI being maliciously used to attack global economic and security systems by defensively deploying AI tools. Specifically, it leverages an unreleased general-purpose model, Claude Mythos Preview, to identify and fix vulnerabilities in critical software worldwide. The model has already detected thousands of exploitable vulnerabilities across mainstream operating systems and browsers. Source
Adobe introduces Student Spaces learning tool
On April 7, Adobe officially launched Student Spaces, an AI-powered learning suite designed for education. The tool allows users to upload PDFs, documents, presentations, spreadsheets, web links, handwritten notes, and transcripts to automatically generate flashcards, mind maps, quizzes, study guides, and editable presentations powered by Adobe Express. It also integrates the AI podcast feature introduced last month, enabling users to convert study materials into listenable audio content.
Student Spaces is currently in free testing. Users can access it via a standalone URL without logging in, and it supports both the Acrobat web version and mobile browsers. Source
360doc to shut down service on May 1
On April 1, the 360doc Personal Library website announced it will cease operations, stating that it was unable to find a suitable party to take over the service while ensuring data security and continuity. All services will officially shut down on May 1, 2026. Starting immediately, 360doc has suspended new content publishing, but login, data backup, VIP refund requests, and wallet withdrawal functions remain available. Source
Cyberpunk 2077 receives PS5 Pro enhanced update
On April 7, CD PROJEKT RED announced via an official blog post a free PS5 Pro enhanced update for Cyberpunk 2077. This update introduces support for PSSR upscaling technology and implements BVH8 architecture optimized for PS5 Pro hardware, improving the accuracy of ray-traced lighting, shadows, and reflections. The game now features three rendering modes: the Ray Tracing Pro mode enables all ray tracing effects, including ambient occlusion, global illumination, and emissive lighting, targeting 40fps on VRR displays (30fps on standard displays); the Performance mode maintains high visual fidelity while using PSSR to boost frame rates up to 90fps (VRR required); and the Ray Tracing mode serves as a balanced option, preserving some ray tracing enhancements while delivering a stable 60fps experience.
The update is available starting today, and the game has also been added to the PlayStation Plus catalog. Source

After updating to the latest stable version, users can right-click the window and select “Move tabs to the side” to enable the feature. This update also includes a revamped Reading Mode, offering a more focused, distraction-free text reading experience. Source
- On April 6, The New Yorker published a 16,000-word investigative report by Ronan Farrow and Andrew Marantz. Based on interviews with more than 100 sources and private memos from figures such as Ilya Sutskever and Dario Amodei, the report alleges systematic deception by OpenAI CEO Sam Altman, including withholding safety protocol details from the board, forming a secret agreement with Greg Brockman to bypass board oversight, and failing to fulfill commitments to allocate compute resources to the Superalignment team.

- According to a recent analysis cited by Ars Technica from The New York Times, Google’s AI Overviews feature has an error rate of around 10% when answering queries. This means that roughly one in ten responses may contain incorrect information. While the system is accurate about 90% of the time, Google’s massive user base means that even a 10% error rate results in hundreds of thousands of incorrect responses being delivered to users worldwide every minute.
