No,

From the note 7662491.8:

"The fix prevents this corruption to be introduced in the redo and
*will not fix any existent* corruption that is already introduced in
the redo/archived logs. Meaning that if the patch is installed and a
recovery is attempted again using the same archived logs, the error
will be still produced."

>> select from table would still give an error, wouldn't it ?

Yes,Patch wouldn't fix anything that is already corrupt. Note suggests
to use dbms_repair to skip corrupt blocks.

>> There is no fix for the root cause ?

Patch would fix the rootcause but that would be of help only in future.
