What is CVE-2026-118604?

The vulnerability arises from a flaw in the framework service of the Alpine iLX-F511, where the system fails to properly validate the length of user-supplied data before copying it into a fixed-length stack-based buffer. This oversight can allow physically present attackers to execute arbitrary code, potentially gaining root access to the device. Authentication is not required to exploit this vulnerability, making it particularly concerning for device security. Refer to advisory ZDI-26-822 for more details on the issue.
