Below is a list of post-release service announcements.
📌 PSA 24/05/26
PSA: We’ve confirmed that the mitigation for CVE-2026-46333 (ssh-keysign-pwn), which prevents unprivileged processes from using the ptrace system call, while intended to address a specific kernel vulnerability, inadvertently prevents Wine and Proton from functioning, directly affecting game compatibility.
Bug Tracker ID: #230
Affected ISO Releases
- nitrux-contemporary-cachy-mesa-b2e8760c-amd64
- nitrux-contemporary-cachy-nvopen-3cf503e8-amd64
Workaround for Existing Users
If you downloaded and installed either of the affected ISO files, please follow the steps below to restore compatibility. This process adjusts the parameter to 1, allowing Wine and Proton to manage their internal memory requirements safely. Level 1 enables restricted ptrace, which allows processes to attach to other processes only if they have a predefined relationship.
- Open the terminal.
- Enter the root environment by executing:
sudo overlayroot-chroot
- Run the following command to modify the system configuration:
sed -i 's/kernel.yama.ptrace_scope=2/kernel.yama.ptrace_scope=1/' /etc/sysctl.d/99-nx-sysctl-overrides.conf
Type exit to leave the chroot environment.
Reboot your system to apply the changes.
Upcoming ISO Release
We will issue new ISO files shortly to correct this configuration out of the box. The adjustment to the ptrace_scope parameter represents the only change in this upcoming release. Users who download the new ISO will not need to apply the manual workaround.
- Updated ISO files:
- nitrux-contemporary-cachy-mesa-d76f9c00-amd64
- nitrux-contemporary-cachy-nvopen-32deb156-amd64
