Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation within the compare_attr(), mi_new_attt_id(), mi_enum_attr(), mi_format_new() and mi_insert_attr() functions in fs/ntfs3/record.c, within the ni_std(), ni_std5(), ni_find_attr(), ni_enum_attr_ex(), ni_load_attr(), ni_remove_attr(), al_remove_le(), ni_ins_new_attr(), ni_try_remove_attr_list(), ni_create_attr_list(), ni_ins_attr_ext(), ni_insert_attr(), ni_expand_mft_list(), ni_expand_list() and ni_write_inode() functions in fs/ntfs3/frecord.c, within the mi_find_attr() and attr_collapse_range() functions in fs/ntfs3/attrib.c. A local user can perform a denial of service (DoS) attack.
