CVE-2026-118605: Alpine iLX-F511 prh_sdp_service_search_decode Stack-based Buffer Overflow Remote Code Execution Vulnerability
Alpine iLX-F511 prhsdpservicesearchdecode Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Alpine iLX-F511 devices. An attacker must first obtain the ability to pair a malicious Bluetooth device with the target system in order to exploit this vulnerability.
The specific flaw exists within the prhsdpservicesearchdecode function. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-29069.
