Summary
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.

The registration loop exceeds array bounds Add boundary check to prevent registered_fb[FB_MAX] access.
