4Description
In the Linux kernel, the following vulnerability has been resolved: smb: client: Don't log plaintext credentials in cifs_set_cifscreds When debug logging is enabled, cifs_set_cifscreds() logs the key payload and exposes the plaintext username and password. Remove the debug log to avoid exposing credentials.
Analysis
The Linux kernel CIFS client contains an information disclosure vulnerability where debug logging in the cifs_set_cifscreds() function exposes plaintext usernames and passwords in kernel logs when debug logging is enabled. This affects all versions of the Linux kernel with CIFS client support, allowing any local user or administrator with access to kernel logs to recover plaintext SMB credentials. …
