Huge #security #vulnerability in #Linux systems allows an #attacker with #PhysicalAccess to #bypass #SecureBoot and inject #malware onto a system even with #LUKS #FDE.

The mitigation is pretty straight-forward.

For
#Ubuntu at-least (I don't run RedHat/ Fedora):

Edit
/etc/default/grub as root.

In the line that says
GRUB_CMDLINE_LINUX="...", add (or append) panic=0.

Followed by:
sudo update-grub. (Takes effect on reboot).

This will prevent your Linux system from launching a
#DebugShell if an attacker repeatedly enters a wrong passphrase for decrypting your Luks #boot #volume.

The linked article has more information.

K1 dürfte am Tablet mal wieder die Maus-App spielen. Eines der Videos war eine Anleitung für ein #Boot mit Gummiband-Antrieb.

Jetzt habe ich einiges an Bauteilen rumliegen, aber bei so kleinen Wellen und Lagern sah es gerade Recht mau aus.

Also einen alternativen Antrieb verbaut!

Jetzt fährt das Boot nur bei voller Sonne, dafür dann ausdauernder - und im Gegensatz zur Anleitung hat es eine Ruderfinne die man auf einen festen Winkel stellen kann.

Another bold move from Fedora: a new proposal aims to drop UEFI boot support on MBR for x86_64 in Fedora 43 💽

It won’t affect existing installs—but new ones via Anaconda will require GPT. The reason? Simplify code and avoid firmware-related crashes.

As with 32-bit, niche setups risk being quietly deprecated. Speak now or lose flexibility later.

#Microsoft has fixed the dual-booting bug affecting Windows and Linux with patch KB5058385, released nine months after the issue was reported.

This update prevents legitimate Linux bootloaders from being blocked.

However, the long delay raises concerns about Microsoft's commitment to niche user needs.

Will they prioritize core features over essential fixes for dual-boot users?

Frage an Linux-Spezialisten:

Ein Kursteilnehmer möchte es so einrichten, dass er seinen Computer wie bisher hochfährt mit Windows, aber wenn eine Linux-SSD drin ist, diese gestartet wird.

Also quasi das Verhalten eines Live-Sticks - nur eben mit einem vollständig installierten Linux.

Nach meinen ersten Versuchen scheint die Sache nicht so einfach zu sein (evtl. müsste ich wohl die GRUB-Config per Hand ergänzen).

Jedenfalls lässt sich das 1:1-Verhalten eines Live-Sticks

A boat at the beach of Imbassaí (Bahia, Brazil) during sunset.
Imbassaí is wonderful small village directly by the Atlantic Ocean approximately 80 km north of Salvador. The former indigenous village has become a touristic center in the region, due to its amazing location and beauty. It’s directly located where a river with the same name (Imbassaí) flows into the ocean. The river separates the beaches, which are located on an offshore island, from the land. That means if you’re on the beach island you can choose between the wild saltwater of the Atlantic Ocean or the calm sweet water of the Imbassaí river.
