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 probing the Tegra Display Serial Interface (DSI) controller. This vulnerability in the tegra_dsi_ganged_probe function can lead to a reference leak, potentially causing memory leaks and resource exhaustion.
Vulnerability Detail
The vulnerability arises from a reference leak in the tegra_dsi_ganged_probe function of the drm/tegra package. When the function is called, it fails to properly release a reference, leading to a memory leak. An attacker could potentially exploit this vulnerability to exhaust system resources, resulting in denial of service or other malicious activities. The vulnerability was introduced in version v3.19 of the Linux Kernel and has been fixed in version v5.16.19 by commit cd78b74031cbc94133965f1017deb822657fc1a6.
