Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
jfs: truncate good inode pages when hard link is 0<br />
<br />
The fileset value of the inode copy from the disk by the reproducer is<br />
AGGR_RESERVED_I. When executing evict, its hard link number is 0, so its<br />
inode pages are not truncated. This causes the bugon to be triggered when<br />
executing clear_inode() because nrpages is greater than 0.
