Description
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.
