The lesson here being... compile your own kernel from git sources every few days?

Give up entirely on non-virtualized container security?

This is not sarcasm. I'd finally given in and started learning about docker/podman-style OCI containerization last week.

in this specific case, they offer an alternative mitigation if your chosen distro has not updated yet:

For immediate mitigation, block AF_ALG socket creation via seccomp or blacklist the algif_aead module:

    echo "install algif_aead /bin/false" > /etc/modprobe.d/disable-algif-aead.conf
    rmmod algif_aead 2>/dev/null

Thanks!

I'd do 'umask 133' in front of the echo out of paranoia.

Out of curiosity, was the asterisk after '2>/dev/null' intentional? I had not seen that idiom before.

		the asterisk is my oops, trying to format the comment in italics to differentiate my comment from the text provided by the author. sorry for the confusion
