SUSE CVE-2025-58356

Constellation is the first Confidential Kubernetes. The Constellation CVM image uses LUKS2-encrypted volumes for persistent storage. When opening an encrypted storage device, the CVM uses the libcryptsetup function cryptactivatebypasshrase. If the VM is successful in opening the partition with th...

Improper Verification of Cryptographic Signature

Overview Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to unsafe handling of null keyslot algorithms in the cryptactivatebypassphrase function. An attacker can gain unauthorized access to unencrypted persistent storage by exploiting the...

CVE-2025-58356

Constellation uses LUKS2-encrypted volumes for persistent storage in a Confidential Kubernetes setup. The vulnerability arises when opening an encrypted device via crypt_activate_by_passhrase because cryptsetup 2.8.1 mishandles null keyslot algorithms, which can cause a volume to be opened withou...

Constellation has insecure LUKS2 persistent storage partitions which may be opened and used

Summary A malicious host may provide a crafted LUKS2 volume to a confidential computing guest that is using the OpenCryptDevice feature. The guest will open the volume and write secret data using a volume key known to the attacker. The attacker can also pre-load data on the device, which could...
