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.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is an out-of-bounds array access in the hp-bioscfg driver of the Linux kernel. Specifically, the hp_populate_*_elements_from_package() functions parse ACPI packages using arrays and loops, but the bounds checking only validated the base index without accounting for additional offsets. This caused the functions to potentially read beyond the valid array limits, leading to out-of-bounds access.


How can this vulnerability impact me? :

The vulnerability can lead to out-of-bounds memory access, which may cause system instability, crashes, or potentially allow an attacker to execute arbitrary code or cause denial of service by exploiting the improper array bounds checking in the hp-bioscfg driver.
