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 hppopulate*elementsfrom_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 enumobj/integerobj/orderobj/passwordobj/string_obj arrays.
When processing multi-element fields like PREREQUISITES and ENUMPOSSIBLEVALUES, these functions read multiple consecutive array elements using expressions like 'enumobj[elem + reqs]' and 'enumobj[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.
