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.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

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?
