CVE-2026-64245

A flaw was found in the Linux kernel's framebuffer device fbdev subsystem. Specifically, within the fbfindmode function, a use-after-free UAF vulnerability exists. This occurs because a memory buffer is released while still being referenced, potentially allowing an attacker to access or manipulat...
