CVE-2021-3979: Fedoraproject Fedora

Medium severity, CVSS 6.5. EPSS: 0.6% chance of exploitation in the next 30 days.

A key length flaw was found in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed in an encryption algorithm to create a non random key, which is weaker and can be exploited for loss of confidentiality and integrity on encrypted disks.
