If I understand correctly, no and no.
If I'm not mistaken, the vulnerability affects LUKS2 volumes created
using cryptsetup since version 2.2.0, but Tails ships 2.1.

But I might be wrong.

Furthermore, this attack is not doable without control of the storage
(ie, be root on a machine on which the storage is attached), and doesn't
allow for full decryption (but still up to few gigabytes).


This is sensitive topic so please double check what I'm saying!
