Descriptions
In the Linux kernel, the following vulnerability has been resolved:
nommu: pass NULL argument to vma_iter_prealloc()
When deleting a vma entry from a maple tree, it has to pass NULL to
vma_iter_prealloc() in order to calculate internal state of the tree, but
it passed a wrong argument. As a result, nommu kernels crashed upon
accessing a vma iterator, such as acct_collect() reading the size of vma
entries after do_munmap().
This commit fixes this issue by passing a right argument to the
preallocation call.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nommu: pasar argumento NULL a vma_iter_prealloc(). Al eliminar una entrada vma de un árbol maple, tiene que pasar NULL a vma_iter_prealloc() para calcular el estado interno del árbol, pero pasó un argumento incorrecto. Como resultado, los kernels nommu fallaban al acceder a un iterador vma, como acct_collect() que lee el tamaño de las entradas vma después de do_munmap(). Esta confirmación corrige este problema al pasar un argumento correcto a la llamada de preasignación.
