kernel: smb: client: validate dacloffset before building DACL pointers

A flaw was found in the Linux kernel's Server Message Block SMB client. A malicious server can exploit this vulnerability on 32-bit systems by providing a crafted dacloffset value. This can cause a pointer wrap, leading to the dereferencing of invalid Discretionary Access Control List DACL fields...
