Name of the Vulnerable Software and Affected Versions cifs-utils versions through 6.14

Description The issue is related to an information leak when a file contains = (equal sign) characters but is not a valid credentials file, particularly with verbose logging enabled. This can potentially allow a remote attacker to disclose protected information.

Recommendations For versions through 6.14, consider disabling verbose logging as a temporary workaround until a patch is available. Restrict access to files that may contain = characters to minimize the risk of exploitation. Avoid using files with = characters in their content for credential purposes until the issue is resolved.
