Background

The HID (Human Interface Device) betop is a package in the Linux Kernel ecosystem. It provides support for the Betop gamepad. The Betop gamepad is a popular input device used for gaming on Linux systems. This package allows the Linux Kernel to recognize and interact with the Betop gamepad. However, a vulnerability has been discovered in the betop package that could lead to a slab-out-of-bounds write.

Vulnerability Detail

The vulnerability in the betop package is a slab-out-of-bounds write. This type of vulnerability occurs when a write operation exceeds the bounds of a slab, which is a fixed-size block of memory used by the Linux Kernel for memory allocation. An attacker could exploit this vulnerability to write data outside the intended memory region, potentially leading to memory corruption, system crashes, or even remote code execution. The impact and attack plausibility of this vulnerability have not been proven yet.

How To Fix

No fixed version is published for this vulnerability.

The vulnerability in the betop package has been fixed in Linux Kernel version v4.4.286. To fix this vulnerability, users should update their Linux Kernel to the latest version that includes the fix. Users can obtain the updated version from the official Linux Kernel repository. The specific commit that addresses this vulnerability is a4faa7153b87fbcfe4be15f4278676f79ca6e019.
