CVE-2022-3650
Public on
Last Modified:
Description
A privilege escalation flaw was found in Ceph. Ceph-crash.service allows a local attacker to escalate privileges to root in the form of a crash dump, and dump privileged information. This issue can lead to loss of confidentiality, integrity, and availability.
Statement
By sending a specially-crafted request, a locally authenticated attacker could exploit this vulnerability to gain elevated privileges as root. Access to Redhat Openshift Data Foundation container is very limited. Hence, the per-product impact for Red Hat Openshift Data Foundation is set to Moderate.

Attack Complexity | Low | Low |
Privileges Required | Low | Low |
User Interaction | None | None |
Scope | Changed | Unchanged |
Confidentiality Impact | High | High |
Integrity Impact | High | High |
Availability Impact | High | High |
