In the Linux kernel, the following vulnerability has been resolved:
cifs: Fix memory and information leak in smb3_reconfigure()
In smb3_reconfigure(), if smb3_sync_session_ctx_passwords() fails, the function returns immediately without freeing and erasing the newly allocated new_password and new_password2. This causes both a memory leak and a potential information leak.
Fix this by calling kfree_sensitive() on both password buffers before returning in this error case.
