Linux's DRM Panic "Screen of Death" Sees Patches for QR Code Error Messages

Linux 6.10 introduces DRM Panic, a new panic screen for kernel errors and situations where VT support may be disabled. Patches now allow for QR codes of error messages to be displayed, condensing lengthy messages for easier capture with smartphones or bug reports. The QR code handler is written in Rust, offering a new approach within the kernel. This feature has been discussed in the past, with Windows and other systems also exploring QR code integration in error messages. Jocelyn Falempe of Red Hat posted patches for a "qr_code" panic screen, showcasing the functionality in action. The code is currently under review for interested parties. This development aims to enhance error message handling and analysis within the Linux kernel, providing a modern and efficient solution for developers and users alike.

The Dirty Pipe Vulnerability

The Dirty Pipe Vulnerability

The Dirty Pipe Vulnerability (CVE-2022-0847) in Linux kernel versions since 5.8 allowed unauthorized data overwriting in read-only files, fixed in versions 5.16.11, 5.15.25, and 5.10.102. Discovered through CRC errors in log files, it revealed systematic corruption linked to ZIP file headers due to a kernel bug in Linux 5.10. The bug's origin was pinpointed by replicating data transfer issues between processes using C programs, exposing the faulty commit. Changes in the pipe buffer code impacted data transfer efficiency, emphasizing the intricate nature of kernel development and software component interactions.

It's a nice idea. I've had to manually transcribe error messages many times. Also if I never see a screenshot of a console again it will be too soon.

Btw, DRM in this context stands for Direct Rendering Manager (man 7 drm) and not digital rights management.

Took ages to figure out, I wish people would explain acronyms more often..

Whilst I appreciate being able to scan, having no tailback at all means having to scan. That's less accessible.
