CVE-2019-13178
modules/luksbootkeyfile/main.py in Calamares versions 3.1 through 3.2.10 has a race condition between the time when the LUKS encryption keyfile is created and when secure permissions are set.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.69%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
