On 29 April 2026, a high local privilege escalation vulnerability in the Linux kernel, tracked as CVE-2026-31431 and named “Copy Fail”, was publicly disclosed. The vulnerability affects Manjaro Linux since 2017. A public proof-of-concept exploit has been released.
We have patched most of our kernels and released them to our testing and unstable branches:
- patched kernels are: 5.10.254+, 5.15.204+, 6.1.170+, 6.6.137+, 6.12.85+, 6.18.22+, 6.19.12+, 7.0-rc7+
- affected kernels are: 6.1.167_rt62, 6.6.133_rt73, 6.12.79_rt17, 6.17.5_rt7 and lower
Temporary Mitigation
Disable the algif_aead kernel module persistently on all affected systems until a patched kernel is available:
sudo su
echo "install algif_aead /bin/false" > /etc/modprobe.d/disable-algif.conf
rmmod algif_aead 2>/dev/null || true
exit

udev-usb-sync and kernel 7.0-rc
If you experience slow transfers to USB attached disks, remove the package udev-usb-sync. It is not known why the 7.0-rc kernel causes this. There may be a regression of some sort. Awaiting the final release of the 7.0 kernel before jumping to conclusions.
See [Unstable Update] April 2026 thread for more info

The issue is solved with the release of 7.0 kernel
