Last modified
CVE-2021-3979 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 0.44% chance of exploitation in the next 30 days.
