Summary

In the Linux kernel, the following vulnerability has been resolved: platform/x86: hp-bioscfg: Fix kernel panic in GET_INSTANCE_ID macro The GET_INSTANCE_ID macro that caused a kernel panic when accessing sysfs attributes: 1. Off-by-one error: The loop condition used '<=' instead of '<', causing access beyond array bounds. Since array indices are 0-based and go from 0 to instances_count-1, the loop should use '<'. 2. Missing NULL check: The code dereferenced attr_name_kobj->name without checking if attr_name_kobj was NULL, causing a null pointer dereference in min_length_show() and other attribute show functions. The panic occurred when fwupd tried to read BIOS configuration attributes: Oops: general protection fault [#1] SMP KASAN NOPTI KASAN: null-ptr-deref in range
