CVE-2023-38409

A memory corruption flaw was found in set_con2fb_map in drivers/video/fbdev/core/fbcon.c in the Framebuffer Console in the Linux kernel. This flaw allows a local attacker to crash the system, leading to a denial of service.

Mitigation

Mitigation for this issue is to skip loading the affected module "fbcon" onto the system until we have a fix available. This can be done by a blacklist mechanism and will ensure the driver is not loaded at boot time.

How do I blacklist a kernel module to prevent it from loading automatically?
