Background
The drm/tegra package is a component of the Linux Kernel that provides support for NVIDIA Tegra display controllers. It enables the management and rendering of graphics on Tegra-based devices. The tegra_dsi_ganged_probe function is responsible for initializing and configuring the DSI (Display Serial Interface) controller in a ganged mode, where multiple DSI controllers are used together. This vulnerability in the function can lead to a reference leak, potentially causing memory leaks and resource exhaustion.
Vulnerability Detail
The vulnerability in tegra_dsi_ganged_probe arises from a reference leak, which occurs when a reference to an object is not properly released after it is no longer needed. This can result in memory leaks and resource exhaustion over time. An attacker may be able to exploit this vulnerability to exhaust system resources, leading to a denial-of-service condition or other unexpected behavior. The vulnerability was introduced in version v3.19 of the Linux Kernel and has been fixed in version v5.15.33.
