CVE-2026-104035: Red Hat Enterprise Linux 10

Medium severity, CVSS 5.5. EPSS: 0.1% chance of exploitation in the next 30 days.

A flaw was found in SSSD. An issue in the Kerberos Credential Manager (KCM) responder allows a local user to cause a Denial of Service (DoS) by maintaining a persistent connection and repeatedly storing and destroying credentials. Because the service fails to release cached objects from memory when credentials are removed, memory consumption grows continuously, ultimately exhausting available memory and rendering the service unresponsive.
