Deskripsi (NVD)

In the Linux kernel, the following vulnerability has been resolved: platform/x86: hp-bioscfg: Fix out-of-bounds array access in ACPI package parsing The hp_populate_*_elements_from_package() functions in the hp-bioscfg driver contain out-of-bounds array access vulnerabilities. These functions parse ACPI packages into internal data structures using a for loop with index variable 'elem' that iterates through enum_obj/integer_obj/order_obj/password_obj/string_obj arrays. When processing multi-element fields like PREREQUISITES and ENUM_POSSIBLE_VALUES, these functions read multiple consecutive array elements using expressions like 'enum_obj[elem + reqs]' and 'enum_obj[elem + pos_values]' within nested loops. The bug is that the bounds check only validated elem, but did not consider the additional offset when accessing elem + reqs or elem + pos_values. The fix changes the bounds check to validate the actual accessed index.
