Background
The Kernel package is a crucial component of the Linux operating system. It provides the core functionality and interfaces for the system's hardware, software, and processes. The x86/Kconfig file within the Kernel package contains configuration options for the x86 architecture. One of these options is CONFIG_X86_X32_ABI, which enables support for the x32 ABI (Application Binary Interface). The llvm-objcopy tool is used for manipulating object files. However, a vulnerability has been discovered where CONFIG_X86_X32_ABI is enabled alongside llvm-objcopy, leading to potential security issues.
Vulnerability Detail
The vulnerability arises when CONFIG_X86_X32_ABI is set to 'y' while using llvm-objcopy. This combination can result in security vulnerabilities, although the specific impact and attack vectors have not been proven. It is important to note that this vulnerability has been fixed in Linux Kernel version v5.16.20 by commit 2141b80328b45f7bfe9691de7804988b4b4b1262.
How To Fix
