CVE-2026-118603

Full vulnerability record from the local CVENow database.

Description

Alpine iLX-F511 vCard Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected Alpine iLX-F511 devices. User interaction is required to exploit this vulnerability in that the target must connect to a malicious Bluetooth device. The specific flaw exists within the parsing of vCard data. The issue results from the lack of proper validation of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-29017.
