Name of the Vulnerable Software and Affected Versions Calamares versions 3.1 through 3.2.10

Description The issue is related to a race condition in the creation and permission setting of the LUKS encryption keyfile. This occurs between the time the keyfile is created and when secure permissions are set, potentially exposing the keyfile to unauthorized access.

Recommendations For Calamares versions 3.1 through 3.2.10, consider applying secure permissions immediately after creating the LUKS encryption keyfile to mitigate the risk of exploitation. As a temporary workaround, restrict access to the keyfile until a patch is available.
