CVE-2023-0751 Information

Description

When GELI reads a key file from standard input it does not reuse the key file to initialize multiple providers at once resulting in the second and subsequent devices silently using a NULL key as the user key file. If a user only uses a key file without a user passphrase the master key is encrypted with an empty key file allowing trivial recovery of the master key.
