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

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

• On April 7, Google announced the introduction of native vertical tabs in the Chrome browser. 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.
