There is no fixed version for Centos:8 kernel-modules.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-modules package and not the kernel-modules package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

fbdev: fix potential buffer overflow in do_register_framebuffer()

The current implementation may lead to buffer overflow when:

  1. Unregistration creates NULL gaps in registered_fb[]
  2. All array slots become occupied despite num_registered_fb < FB_MAX
  3. The registration loop exceeds array bounds

Add boundary check to prevent registered_fb[FB_MAX] access.
