Reports emerged of YouTube causing browsers to freeze and use excessive RAM due to a suspected bug in the platform's interface code. Users across various browsers experienced stuttering videos, unresponsive tabs, and system slowdowns while on YouTube. Investigations suggest that a bug in the video controls section of the interface may be causing browsers to get stuck in a loop of continuous layout recalculations. This issue, known as layout thrashing, can lead to high CPU and memory usage, causing severe browser performance issues. Mozilla developers are still looking into the problem, with no confirmed fix available yet, and the exact cause remains unofficial.

Dell SupportAssist update is crashing PCs with constant blue screens and reboot loops — the boot service built for system recovery is the culprit of unending instability

A recent update to Dell's SupportAssist Remediation software is causing constant blue screen errors and reboot loops on various Dell laptop models. The issue stems from the update version 5.5.16.0 released on April 30th, affecting systems like the XPS 15 9530 and Dell Pro Plus 14. Users have identified the culprit as the DellSupportAssistRemedationService.exe process and have found workarounds to stop the crashes, such as disabling the service or uninstalling the software entirely. This isn't the first time SupportAssist Remediation has caused such issues, with a similar pattern reported last year. Dell has yet to acknowledge the problem or provide a fix.

RPCS3 updates its contribution guidelines after AI-generated 'slop' pull requests caused regressions in the PS3 emulator

RPCS3, the PlayStation 3 emulator, has updated its contribution guidelines to combat the influx of AI-generated code submissions causing regressions in the project. The team now requires contributors to fully comprehend and take ownership of the code they submit, even if AI was involved in its creation. The guidelines do not ban AI-generated code but mandate disclosure and responsibility from contributors. RPCS3 emphasized the need for quality submissions to prevent bugs and performance issues. The project, driven by unpaid volunteers, aims to maintain its progress in emulating the complex Cell CPU architecture.

Linux bitten by second severe vulnerability in as many weeks

A new Linux vulnerability named Dirty Frag allows low-privilege users to gain root access on servers, posing a significant threat, especially in shared environments. The exploit code, leaked online, works reliably across various Linux distributions and has caught the attention of hackers in the wild. The deterministic nature of the exploit makes it stealthy and dangerous, similar to a previous vulnerability called Copy Fail. Security experts urge organizations to apply patches and implement mitigations promptly to safeguard their systems. While some distributors have released patches, users are advised to check with their official provider for updates.
