As people rightly highlight that the #CopyFail fix status in various #Linux distros is… confusing, it’s worth keeping in mind you can deploy the workaround everywhere with no side effects:
# echo "install algif_aead /bin/false" > /etc/modprobe.d/disable-algif.conf # rmmod algif_aead 2>/dev/null || true
By ‘confusing’ I mean:
after reading #Ubuntu https://ubuntu.com/security/CVE-2026-31431 I have no idea whether my specific distro is vulnerable or not (WTF are these linux-hwe code names, my lsb_release just says Ubuntu)
Amazon Linux is at least quite open about ‘fix pending’ https://explore.alas.aws.amazon.com/CVE-2026-31431.html
@kravietz IIRC these packages specify their flavor in uname -r, so it still should be trivial.
@dos On my laptops’ 25.10 it is quite clear by elimination but on server cloud distros like 22.04 or 24.04 LTS installed by Hetzner I’m not so sure.
