Background
The Linux kernel is a critical component of the Linux operating system, responsible for managing system resources and facilitating communication between hardware and software. It is widely used in various distributions, including Android. The vulnerability identified as CVE-2022-24958 affects the Linux kernel and specifically impacts the dev_config function in inode.c. This vulnerability allows for arbitrary code execution due to a use after free issue, potentially leading to local privilege escalation without requiring additional execution privileges. Exploitation of this vulnerability does not require user interaction.
Vulnerability Detail
The vulnerability arises from a use after free issue in the dev_config function of inode.c. When certain conditions are met, the function fails to properly handle a freed object, resulting in a situation where an attacker can execute arbitrary code. This can be leveraged to escalate privileges locally, potentially gaining unauthorized access to sensitive system resources. The vulnerability was introduced in an earlier version of the Linux kernel and has been fixed in subsequent updates.
