*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
smb: client: mask server-provided mode to 07777 in modefromsid<br />
<br />
When modefromsid is active, parse_dacl() applies the server-provided<br />
sub_auth[2] value from the NFS mode SID to cf_mode without masking to<br />
07777. Apply the correct masking, same as in the read path.
