Descriptions

In the Linux kernel, the following vulnerability has been resolved: jfs: fix array-index-out-of-bounds in dbFindLeaf Currently while searching for dmtree_t for sufficient free blocks there
is an array out of bounds while getting element in tp->dm_stree. To add
the required check for out of bound we first need to determine the type
of dmtree. Thus added an extra parameter to dbFindLeaf so that the type
of tree can be determined and the required check can be applied.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: jfs: corrige el índice de matriz fuera de los límites en dbFindLeaf. Actualmente, mientras se busca dmtree_t para suficientes bloques libres, hay una matriz fuera de los límites al obtener el elemento en tp->dm_stree . Para agregar la verificación requerida para fuera de los límites, primero debemos determinar el tipo de dmtree. Por lo tanto, se agregó un parámetro adicional a dbFindLeaf para que se pueda determinar el tipo de árbol y se pueda aplicar la verificación requerida.
