Summary
cifs-utils security update
Details

The in-kernel CIFS filesystem is generally the preferred method for mounting SMB/CIFS shares on Linux.

Security Fix(es):

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.(CVE-2025-2312)
