Cloudron Forum

Hello @nicholasfrank Always happy to help.

Hello @timconsidine I have posted the announcement here: https://forum.cloudron.io/topic/15442/ubuntu-24.04-kernel-6.8.0-110-regression-affecting-cloudron

Hello everyone. Glad the issue is now fixed. FYI I've received yesterday a legit notification from Hostinger mentioning the following: **Linux kernel vulnerability disclosed (CVE-2026-31431)** A security flaw called "Copy Fail" (CVE-2026-31431) has been found in the Linux kernel. It affects nearly all major Linux distributions – including Ubuntu, Debian, RHEL, Amazon Linux, SUSE, Fedora, and more – on any kernel built between 2017 and today. The vulnerability lets a local user gain full admin access to a server. It can also affect containerized environments. The fix takes just a few minutes. Option 1: Update your kernel (recommended) For Ubuntu/Debian: sudo apt update, sudo apt upgrade -y For RHEL-based systems: sudo yum update Then reboot your server. Option 2: Disable the affected module (temporary fix) If updating right now isn't an option, disable the vulnerable module to reduce exposure: echo "install algif_aead /bin/false" > /etc/modprobe.d/disable-algif.conf rmmod algif_aead 2>/dev/null || true This won't affect SSH, TLS, LUKS, or OpenSSL." I'm wondering. Is this issue already addressed by Cloudron's latest updates or should I apply the fix myself ? Thanks for your support and happy workers' Day

Cheers, yes I've added the r8125 module to that now. I'll see what happens next time I need to restart. I haven't had to either, must be my cheap hardware choices biting me in the ass.

@nj Cloudro relies on Ubuntu LTS versions and security updates are enabled automatically (independent from Cloudron releases). So once the ubuntu securty team updates the kernels, all Cloudrons will get is as well. Since this is a kernel issue, you will likely see some "reboot required" notification in your Cloudron dashboard afterwards.

@d19dotca I think the -f flag on install just "cleans up" the installation : it notices that some files required for some packages were removed (in the previous line), so it removes said packages. What actually frees up the space is the rm. The apt-get -f install just makes the system notice that the packages in question are not installed anymore
