Description
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.
Affected configurations
• linux linux kernel (>= 2.6.12.1 < 6.1.149)
• linux linux kernel (>= 6.2 < 6.6.103)
• linux linux kernel (>= 6.7 < 6.12.43)
• linux linux kernel (>= 6.13 < 6.15.11)
• linux linux kernel (>= 6.16 < 6.16.2)
