Buffer Overflow Vulnerability in Linux Kernel's Framebuffer Management

CVE-2025-38702

What is CVE-2025-38702?

A potential buffer overflow vulnerability has been identified in the Linux kernel's framebuffer management. This issue arises when unregistration leads to NULL gaps in the registered framebuffer array, allowing the registration process to exceed defined array bounds. Consequently, this flaw could potentially result in memory access violations and system instability. Implementing boundary checks is crucial to prevent unauthorized access and mitigate the risks associated with this vulnerability.
