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 functionalities, such as device drivers, memory management, and process scheduling. The tty subsystem within the Kernel handles input and output operations for terminal devices. The goldfish driver is specifically designed for the Android emulator environment. However, a vulnerability has been discovered in the goldfish driver that can lead to potential security risks.
Vulnerability Detail
The vulnerability in the goldfish driver arises from the improper destruction of the tty port. Instead of using the appropriate function tty_port_destroy(), an incorrect method is employed, leaving the port vulnerable to exploitation. The impact and attack plausibility of this vulnerability have not been proven yet. However, it is crucial to address this issue to prevent any potential security breaches. The vulnerability was introduced in version v3.9 of the Linux Kernel and has been fixed in version v5.18.4.
How To Fix
No fixed version is published for this vulnerability.
To fix this vulnerability, it is necessary to update the Linux Kernel to version v5.18.4 or later. This update includes the commit 4639d1b992de8f37d66f698056875c274efcd45f, which resolves the issue by using the correct function tty_port_destroy() to destroy the port.
