Description
In the Linux kernel, the following vulnerability has been resolved: cifs: Fix the error length of VALIDATE_NEGOTIATE_INFO message Commit d5c7076b772a ("smb3: add smb3.1.1 to default dialect list") extend the dialects from 3 to 4, but forget to decrease the extended length when specific the dialect, then the message length is larger than expected.
