CVE-2024-38119 is a critical remote code execution vulnerability in the Windows Network Address Translation (NAT) component. The flaw is caused by a use-after-free condition in the Windows NAT implementation, where memory that has already been released can subsequently be accessed in a way that corrupts program state. Successful exploitation can allow an attacker to execute arbitrary code on the target system. Available reporting indicates the issue affects supported Windows platforms that include the vulnerable NAT code path, and exploitation is considered less likely due to the required attack conditions.
