Two callers of ext3_msg omit the prefix and pass the format string as the second parameter and the first parameter to the format string as the third parameter. In both cases this string comes from an arbitrary source. Which means the string may contain format string characters, which will lead to undefined and potentially harmful behavior. The issue was introduced in commit 4cf46b67eb("ext3: Unify log messages in ext3") and is fixed by this patch.
