Description
In the Linux kernel, the following vulnerability has been resolved:
udf: Fix preallocation discarding at indirect extent boundary
When preallocation extent is the first one in the extent block, the
code would corrupt extent tree header instead. Fix the problem and use
udf_delete_aext() for deleting extent to avoid some code duplication.
