CVE-2026-49796 is a critical heap-based buffer overflow vulnerability in Windows GDI+. The flaw arises from improper handling of memory in the GDI+ graphics processing component, leading to a heap corruption condition. Microsoft classifies the issue under remote code execution, although the available details indicate successful exploitation results in local code execution by an unauthorized attacker on an affected system. As a memory corruption vulnerability in a widely used graphics subsystem, exploitation could allow attacker-controlled data to overwrite heap memory structures and redirect execution flow.
