Background

The linux-libc-dev package is a development package that provides the necessary header files and libraries for compiling programs that use the Linux kernel's C library interface. It is an essential component for building and running applications on Linux systems. The package is widely used and is included in various Linux distributions.

This vulnerability affects the linux-libc-dev package version 6.1.90-1.

Vulnerability Detail

The vulnerability in the linux-libc-dev package is related to the DMCUB (Display Micro Controller Unit Block) enter/exit idle interface in the drm/amd/display module of the Linux kernel. The issue arises when attempting to send commands while the DMCUB is not powered on, leading to a potential hang.

To address this, the developers have refactored the DMCUB enter/exit idle interface to ensure that the idle state is exited before sending any commands. This prevents the possibility of entering an infinite loop and resolves the vulnerability.

The vulnerability has a CVSS score of 4.4, indicating a medium severity level.

How To Fix
