Background
linux-libc-dev is a package that provides the Linux kernel headers for development. It allows developers to compile and build applications that interact with the Linux kernel. This package is an essential component for building and running software on Linux systems. However, a vulnerability has been discovered in the drm/amd module of the Linux kernel, which is included in the linux-libc-dev package.
Vulnerability Detail
The vulnerability in the drm/amd module of the Linux kernel allows for an array index out of bounds issue when updating the pcie parameter. In certain scenarios, such as in an SR-IOV environment, the value of pcie_table->num_of_link_levels can be 0, causing the array index to go out of bounds. This vulnerability can potentially be exploited by an attacker to execute arbitrary code or cause a denial of service.
