Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> udf: Do not bother merging very long extents<br /> <br /> When merging very long extents we try to push as much length as possible<br /> to the first extent. However this is unnecessarily complicated and not<br /> really worth the trouble. Furthermore there was a bug in the logic<br /> resulting in corrupting extents in the file as syzbot reproducer shows.<br /> So just don&amp;#39;t bother with the merging of extents that are too long<br /> together.
