Descriptions

The (1) hugetlb_vmtruncate_list and (2) hugetlb_vmtruncate functions in fs/hugetlbfs/inode.c in the Linux kernel before 2.6.19-rc4 perform certain prio_tree calculations using HPAGE_SIZE instead of PAGE_SIZE units, which allows local users to cause a denial of service (panic) via unspecified vectors.

Las funciones (1) hugetlb_vmtruncate_list y (2) hugetlb_vmtruncate en fs/hugetlbfs/inode.c del núcleo de Linux anterior a 2.6.19-rc4 realiza determinados cálculos prio_tree usando unidades HPAGE_SIZE en lugar de PAGE_SIZE, lo cual permite a usuarios locales provocar una denegación de servicio (panic) a través de vectores no especificados.
