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. This vulnerability affects the linux-libc-dev package version 6.1.90-1.
Vulnerability Detail
The vulnerability identified as CVE-2024-26914 in the linux-libc-dev package arises from an incorrect array size in the drm/amd/display component of the Linux kernel. The mpc_combine array, which records all the planes per asic, is mistakenly sized using MAX_SURFACES instead of MAX_PLANES. This leads to an array overflow when there are more than 3 planes. An attacker could potentially exploit this vulnerability to cause a denial of service (DoS) or execute arbitrary code.
