Buffer Overflow Vulnerability in Linux Kernel Affecting Intel Graphics

CVE-2023-53678

What is CVE-2023-53678?

A vulnerability in the Intel Graphics Driver within the Linux kernel can lead to a buffer overflow during system suspend operations. Specifically, if the framebuffer device (fbdev) is not initialized, an attempt to suspend can cause a NULL pointer dereference, potentially affecting system stability and performance. This issue occurs on platforms without an active display, where the fbdev suspend function should be bypassed. A patch has been introduced to ensure that suspending fbdev is contingent upon the display's presence, effectively mitigating the risk of system crashes and unexpected behavior.
