Background
The drm/meson component is part of the Linux Kernel, which is responsible for managing graphics and display devices. It provides support for various hardware platforms and drivers. The vulnerability in question affects the shutdown process when a component is not probed properly. This can lead to a crash during shutdown, potentially causing system instability or data loss.
Vulnerability Detail
The vulnerability arises from a flaw in the drm/meson component, specifically in the shutdown handling code. When a component is not probed correctly, the shutdown process triggers a crash. An attacker could potentially exploit this vulnerability to disrupt the normal shutdown sequence, leading to system instability or denial of service. The impact and attack plausibility of this vulnerability have not been proven yet.
How To Fix
No fixed version is published for this vulnerability.
To fix this vulnerability, it is recommended to update the Linux Kernel to version v5.4.124 or later. The fix for this issue was implemented in commit 4ce2bf20b4a6e307e114847d60b2bf40a6a1fac0. Updating to the latest stable version of the Linux Kernel will ensure that the vulnerability is patched.
