This issue may lead to disclosing sensitive data from the host's Kerberos credentials cache.

MEDIUM 5.9EPSS 0.21%

Does this matter?

Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.

Description

A flaw was found in cifs-utils. When trying to obtain Kerberos credentials, the cifs.upcall program from the cifs-utils package makes an upcall to the wrong namespace in containerized environments. This issue may lead to disclosing sensitive data from the host's Kerberos credentials cache.
