Description OSIDB Bzimport 2026-05-08 15:03:53 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ksmbd: Don't log keys in SMB3 signing and encryption key generation

When KSMBD_DEBUG_AUTH logging is enabled, generate_smb3signingkey() and
generate_smb3encryptionkey() log the session, signing, encryption, and
decryption key bytes. Remove the logs to avoid exposing credentials.
