Background
The Kernel is a crucial component of the Linux operating system that acts as a bridge between the hardware and software layers. It provides essential services and functions, such as device drivers, memory management, and process scheduling. The Kernel is responsible for managing system resources and ensuring the stability and security of the operating system. However, a vulnerability has been discovered in the Kernel that could potentially compromise the security of the system.
Vulnerability Detail
The vulnerability identified as ARM: 9210/1 affects the Kernel in Linux. It arises from the failure to mark the FDT_FIXED sections as shareable. This vulnerability can be exploited by an attacker to gain unauthorized access to sensitive information or execute arbitrary code on the affected system. The lack of proper section marking allows an attacker to manipulate the memory layout and potentially bypass security mechanisms. This vulnerability has the potential to lead to privilege escalation, denial of service, or information disclosure.
How To Fix
No fixed version is published for this vulnerability.
To fix this vulnerability, it is recommended to update the Linux Kernel to version v5.4.207 or later. The fix for this vulnerability was implemented in commit 0f02e7c02bb037ef7081534605405dfe173947bf. Updating the Kernel to the latest version ensures that the FDT_FIXED sections are correctly marked as shareable, mitigating the vulnerability.
